Functionalization of Piperidine Derivatives for the Site-Selective and Stereoselective Synthesis of Positional Analogues of Methylphenidate

Rhodium-catalyzed C-H insertions and cyclopropanations of donor/acceptor carbenes have been used for the synthesis of positional analogues of methylphenidate. The site selectivity is controlled by the catalyst and the amine protecting group. C-H functionalization of N-Boc-piperidine using Rh-2(R-TCPTAD)(4), or N-brosyl-piperidine using Rh-2(R-TPPTTL)(4) generated 2-substitited analogues. In contrast, when N-alpha-oxoarylacetyl-piperidines were used in combination with Rh-2(S-2-Cl-5-BrTPCP)(4), the C-H functionalization produced 4-susbstiuted analogues. Finally, the 3-substituted analogues were prepared indirectly by cyclopropanation of N-Boc-tetrahydropyridine followed by reductive regio- and stereoselective ring-opening of the cyclopropanes.

Generation and Alkylation of alpha-Carbamyl Radicals via Organic Photoredox Catalysis

Strategies for the direct C-H functionalization of amines are valuable as these compounds comprise a number of pharmaceuticals, agrochemicals and natural products. This work describes a novel method for the C-H functionalization of carbamate-protected secondary amines via a-carbamyl radicals generated using photoredox catalysis. The use of the highly oxidizing, organic acridinium photoredox catalyst allows for direct oxidation of carbamate-protected amines with high redox potentials to give the corresponding carbamyl cation radical. Following deprotonation, the resultant open-shell species can be intercepted by a variety of Michael acceptors to give elaborate alpha-functionalized secondary amines. The reaction proceeds under mild conditions without the requirement of exogenous redox mediators or substrate prefunctionalization. Additionally, we were able to showcase the utility of this methodology through the enantioselective synthesis of the indolizidine alkaloid, (+)-monomorine I.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 124172-53-8.

The reactions of chlorine dioxide with inorganic and organic compounds in water treatment: kinetics and mechanisms

Chlorine dioxide (ClO2), as an alternative to chlorine, has been widely applied in water treatment. In order to better understand the performance of ClO(2)in water treatment, the kinetics and mechanisms of ClO(2)reactions with inorganic and organic compounds found in waters are critically reviewed. In the case of inorganic compounds, ClO(2)reacts with I-, CN-, NO2-, SO32-, Fe(ii) and Mn(ii) rapidly at apparent second-order reaction rate constants (k(app)) of 10(2)-10(6)M(-1)s(-1)at pH 7.0 and barely reacts with NH(4)(+)and Br-. In the case of organic compounds, ClO(2)selectively reacts with compounds with electron-rich moieties, such as phenols (k(app)= 10(3)-10(9)M(-1)s(-1)), anilines (k(app)= 10(5)-10(8)M(-1)s(-1)), and thiols (k(app)> 10(8)M(-1)s(-1)). ClO(2)also shows high reactivity towards aliphatic tertiary amines and heterocyclic nitrogenous compounds (i.e., indoles and piperidines) withk(app)of 10(1)-10(6)M(-1)s(-1)at pH 7.0, but low reactivity with unsaturated structures (i.e., olefins and aldehydes). Thek(app)values at pH 7.0 in ClO(2)oxidation vary over 14 orders of magnitude. Electron transfer is the dominant pathway for ClO(2)reactions. Quantitative structure-activity relationships (QSARs) can be used to predict the species-specific secondary reaction rate constants for ClO(2)oxidation of compounds containing phenolic and amine structures. Little modifications are expected on the structure of the parent compounds upon the primary attack of ClO2, but further oxidation generally leads to the formation of quinones, aldehydes and carboxylic acids. Furthermore, the transformation kinetics of inorganic compounds, typical organic compounds and emerging micropollutants are compared and their half-life times under typical water treatment conditions during ClO(2)oxidation are calculated.

An Ultrasound-assisted Nanocatalysis: Ag NPs/rGO Nanocomposite Catalyzed One-pot Diastereoselective Synthesis of Functionalized Tetrahydropyridines

Ag NPs decorated reduced graphene oxide (Ag NPs/rGO) composite was synthesized through one-pot protocol involving simultaneous reduction of GO and AgNO3 and characterized by X-ray diffraction, transmission electron microscope, scanning electron microscopy, ultraviolet-visible, Fourier transform infrared, Raman, CV, and energy dispersive X-ray analyses. Results indicated that Ag NPs (similar to 30 nm) were unvaryingly distributed onto the surface of rGO with good dispersion capability that usually lacks in Ag NPs alone. These nanocomposites were exploited to study their catalytic activities toward the one-pot diastereoselective synthesis of functionalized tetrahydropyridines under ultrasonic irradiation (US). The catalytic activity of Ag NPs/rGO was about 22-fold higher under US as compared to conventional method. Antiselectivity, shorter reaction time, excellent yields, simple work-up procedure, and purification of products by non-chromatographic methods were inherent advantages of the protocol. The catalyst was reused up to four runs without an appreciable loss of catalytic activity. [GRAPHICS] .

Preclinical in vitro and in vivo pharmacokinetic properties of danicamtiv, a new targeted myosin activator for the treatment of dilated cardiomyopathy

Dilated cardiomyopathy (DCM) is a disease of the myocardium defined by left ventricular enlargement and systolic dysfunction leading to heart failure. Danicamtiv, a new targeted myosin activator designed for the treatment of DCM, was characterised in in vitro and in vivo preclinical studies. Danicamtiv human hepatic clearance was predicted to be 0.5 mL/min/kg from in vitro metabolic stability studies in human hepatocytes. For human, plasma protein binding was moderate with a fraction unbound of 0.16, whole blood-to-plasma partitioning ratio was 0.8, and danicamtiv showed high permeability and no efflux in a Caco-2 cell line. Danicamtiv metabolism pathways in vitro included CYP-mediated amide-cleavage, N-demethylation, as well as isoxazole- and piperidine-ring-opening. Danicamtiv clearance in vivo was low across species with 15.5, 15.3, 1.6, and 5.7 mL/min/kg in mouse, rat, dog, and monkey, respectively. Volume of distribution ranged from 0.24 L/kg in mouse to 1.7 L/kg in rat. Oral bioavailability ranged from 26% in mouse to 108% in dog. Simple allometric scaling prediction of human plasma clearance, volume of distribution, and half-life was 0.64 mL/min/kg, 0.98 L/kg, and 17.7 h, respectively. Danicamtiv preclinical attributes and predicted human pharmacokinetics supported advancement toward clinical development.

Recent Advances in the Synthesis of Piperidines: Functionalization of Preexisting Ring Systems

The present review focuses on strategies for the construction of piperidines which have appeared in the literature since 2003 through mid-2017. In a preceding chapter (201 /AFIE 191), we summarized synthetic methods involving the construction of the piperidine ring from essentially acyclic starting materials in an intra- or intermolecular manner. The present chapter aims at giving a general overview of decoration or modification of previously generated pyridines or piperidines. The hydrogenation of preformed pyridine or pyridinium rings and introduction of substituents into fully saturated piperidines as well as ring expansion of pyrrolidines to piperidines are the most prevalent methods.

New insight into the thermal-oxidative stability of polyamide 6: A comparison investigation on the effect of hindered amine and CuI/KI

Polyamide 6 (PA6) and stabilized PA6 with two different thermal stabilizers, (ie, metal salts CuI/KI and hindered amine KYN818 [1,3-benzendicarboxamide,N,N’-bis(2,2,6,6-tetramethyl-4-piperidinyl)]) were separately prepared by melt blending and then aged for different time. The effects of aging temperature and aging time on crystallization behaviors of PA6 and stabilized PA6 were systematically investigated by differential scanning calorimetry and X-ray diffraction. The variations of melting temperature, crystallinity and 2 theta values suggest that aging under high temperature will accelerate the formation of crystals initially and then the degradation of molecular chains. The yellowness index and maximum decomposition temperature of stabilized PA6 are higher than that of PA6, which is dominated by different aging mechanisms and properties of stabilizers. In addition, the viscosity of all systems is increased at the preliminary stage, which is caused by the crosslinking network and the post-polycondensation. The results of dynamic mechanical analysis showed that the glass transition temperature (T-g) decreases because the degradation of molecular chains during the aging process. Moreover, the carbonyl index for stabilized PA6 is lower than PA6, indicating the degradation is hindered by stabilizers. A comparison of the stabilization performance between CuI/KI and KYN818 was investigated to differentiate the long-term stabilizing efficiency.

X-ray Crystal Structure and Hirshfeld Analysis of Gem-Aminals-Based Morpholine, Pyrrolidine, and Piperidine Moieties

The gem-aminals of 1,2-dimorpholinoethane (1) and 1-morpholino-3-morpholinium bromide propane (2) were synthesized by reaction of two molar ratio of morpholine with the halogenating agents in the presence of basic condition (K2CO3) in acetone at room temperature (RT) overnight. The structures of the centro-symmetric compound 1 and the morpholinium salt derivative 2 were assigned unambiguous by single crystal X-ray diffraction analysis and compared with the 1,2-di(pyrrolidin-1-yl)ethane 3 and 1,2-di(piperidin-1-yl)ethane 4. The 1,2-dimorpholinoethane molecule has a center of symmetry at the midpoint of the C-C bond of the ethyl moiety leading to two equivalent halves. It crystallized in monoclinic crystal system and P2(1)/n space group, while the unit cell parameters are determined to be a = 6.0430(3), b = 8.0805(3), c = 11.1700(4) angstrom, and beta = 97.475(2)degrees with unit cell volume of 540.80(4) angstrom(3) and Z = 2 at 170(2) K. The less symmetric analogue 2 crystallized in the lower space group P2(1) with unit cell parameters of a = 6.37450(10), b = 11.1378(2), c = 9.6549(2) angstrom, and beta = 93.358(2)degrees, while the unit cell volume is 684.30(2)angstrom(3) at 120(2) K. Using Hirshfeld analysis, the molecules of 1 are mainly packed by weak N horizontal ellipsis H (4.2%), O horizontal ellipsis H (16.8%), and H horizontal ellipsis H (79.0%) interactions. In contrast, the molecules of 2 are packed by significantly short O horizontal ellipsis H (14.4%) and Br horizontal ellipsis H (11.6%) interactions in addition to the relatively long H horizontal ellipsis H (73.3%) interactions. DFT calculations predicted the molecular geometry of the studied compounds showing a good agreement with the experimental X-ray structures. Due to symmetry considerations, compounds 1, 3, and 4 are nonpolar with zero dipole moment, while the less symmetric molecule 2 has a dipole moment of 6.914 Debye. Their electronic aspects, such as natural population charges, HOMO, and LUMO energies as well as the corresponding reactivity descriptors, were also calculated and discussed.
