Addition of Lithium Anion of (Acetylmethylene)triphenylphosphorane to Nonracemic Sulfinimines: Total Synthesis of (+)-241D and Formal Total Synthesis of (+)-Preussin

The addition of lithium anion of (acetylmethylene)triphenylphosphorane to nonracemic sulfinimines was investigated. It was found that the addition proceeded with good diastereoselectivity and further reaction of the formed sulfinimidophosphorane with several aldehydes afforded the beta-sulfinamido substituted enones in good yields. The resultant enones were elaborated to the synthesis of alkaloid (+)-241D, to the formal total synthesis of (+)-preussin, and to the synthesis of aminocyclopentenol.

Oxidative Coupling-Thionation of Amines Mediated by Iron-Based Imidazolium Salts for the Preparation of Thioamides

An efficient and selective multicomponent oxidative coupling, involving the use of two different amines, sodium phosphate, and elemental sulfur have been described for the preparation of thioamides, employing microwave irradiation. The use of an iron(III)-based imidazolium salt is essential as catalyst. Indeed, the iron-based catalyst is involved in the oxidative coupling of the two amines and in the subsequent C-S bond formation. The protocol is useful for a wide variety of primary benzylamines and alkylamines, as coupling partners. Thus, various electron-rich and electron-poor substituents in the aromatic rings and also fused piperidine derivatives, are suitable starting materials in this reaction. Some of the obtained products are important synthetic intermediates for natural products.

Lysosomes-targeting imaging and anticancer properties of novel bis-naphthalimide derivatives

A series of novel N, N-bis(3-aminopropyl) methylamine bridged bis-naphthalimide derivatives NI1-NI8 containing saturated nitrogenous heterocycles were designed and synthesized, their cytotoxic activities against Hela, MCF-7, A549 and MGC-803 cells were investigated, Compounds NI1-NI4 modified with piperidine and piperazine exhibited good and selective cytotoxic activity, for instance, compounds NI1 and NI4 showed potent cytotoxic activity against Hela cells and MGC-803 cells with the IC50 values of 2.89, 060, 2.73 and 1.60 mu M, respectively, better than the control drug (Amonafide). However, compounds NI5-NI8 conjugated with pyrrole derivatives showed weak cytotoxic activities against the all tested cell lines. Furthermore, their DNA binding properties, fluorescence imaging and cell cycle were investigated. Interestingly, compounds NI1 and NI4 showed fluorescence enhancement because of the strong binding with Ct-DNA, and exhibited fluorescence imaging with Hela cells on the lysosomes.

Synthesis of Isofagomine Derivatives as New Fluorescence pH Indicators/Glycosidase Inhibitors

Inhibitor protonation of azasugars of the isofagomine type when bound to enzyme can be investigated using photon induced electron transfer (PET) quenching of an attached fluorophore. For this purpose, Isofagomine, iso-d-galacto-fagomine, and iso-l-gulo-fagomine were converted toN-(10-chloroanthracenenyl-9-alkyl) derivatives where the alkyl group contained one, two, or three methylene groups. The new derivatives displayed pH dependent fluorescence; as the ammonium forms they were fluorescent, while 90-99 % of the fluorescence was quenched in the amine forms. The 3 isofagomine derivatives were competitive inhibitors ofT. Maritima Iota-glucosidase withK(i)values from 0.37-4.6 tau M. Similarly, the iso-d-galacto-fagomines inhibitedA. Niger Iota-galactosidase withK(i)values from 63-2000 nm. When bound to the enzymes the inhibitors displayed between 1-15 % fluorescence.

Heterocyclic Amine-Induced Feeding Deterrence and Antennal Response of Honey Bees

Simple Summary This study examined the behavioral and antennal effects of heterocyclic amines (HCAs) on forager honey bees. Behavioral changes related to feeding were initially characterized using a video-tracking protocol in which individual foragers were exposed to HCA-treated food sources within a Petri dish arena. The most efficacious HCA was then tested in a field study using a high-tunnel arena to determine whether repellent effects could be observed on a larger number of foragers to a treated food source. The same HCA was then tested in the field on both melon flowers and knapweed bundles to observe whether repellency was conserved in a more agriculturally realistic scenario. Finally, electroantennogram (EAG) experiments were conducted to document whether the honey bee olfactory system was detecting these compounds. These findings suggest that HCAs could provide an active approach to deter honey bee foragers from feeding on treated agricultural crops. The productivity and survival of managed honey bee colonies is negatively impacted by a diverse array of interacting factors, including exposure to agrochemicals, such as pesticides. This study investigated the use of volatile heterocyclic amine (HCA) compounds as potential short-term repellents that could be employed as feeding deterrents to reduce the exposure of bees to pesticide-treated plants. Parent and substituted HCAs were screened for efficacy relative to the repellent N,N-diethyl-meta-toluamide (DEET) in laboratory and field experiments. Additionally, electroantennogram (EAG) recordings were conducted to determine the level of antennal response in bees. In video-tracking recordings, bees were observed to spend significantly less time with an HCA-treated food source than an untreated source. In a high-tunnel experiment, the HCA piperidine was incorporated in a feeding station and found to significantly reduce bee visitations relative to an untreated feeder. In field experiments, bee visitations were significantly reduced on melon flowers (Cucumis melo L.) and flowering knapweed (Centaurea stoebe L.) that were sprayed with a piperidine solution, relative to untreated plants. In EAG recordings, the HCAs elicited antennal responses that were significantly different from control or vehicle responses. Overall, this study provides evidence that HCAs can deter individual bees from food sources and suggests that this deterrence is the result of antennal olfactory detection. These findings warrant further study into structure-activity relationships that could lead to the development of short-term repellent compounds that are effective deterrents to reduce the contact of bees to pesticide-treated plants.

Efficient and Eco-Friendly One-Pot Synthesis of Functionalized Furan-2-one, Pyrrol-2-one, and Tetrahydropyridine Using Lemon Juice as a Biodegradable Catalyst

New and facile one-pot approach for the syntheses of polysubstituted pyrrol-2-one, furan-2-one and tetrahydropyridines (THPDs) from easily available starting materials using lemon juice as a green catalyst is presented. The synthesis of diverse furan-2-one and pyrrol-2-one derivatives were achieved from dialkyl acetylenedicarboxylates, different amines and aldehydes in high yields and short reaction times by employing 0.25 mL of lemon juice at 110 C-degrees under solvent-free condition. THPDs, on the other hand, were synthesized via the reaction among beta-ketoesters, various aromatic aldehydes, and amines in the presence of 0.25 mL of lemon juice in ethanol at room temperature. The molecular structure of compound pyrrol-2-one 7e and THPD 10 g were confirmed by the single crystal X-ray analysis. Application of cheap and green catalyst, environmentally benign reaction condition, good to high yields, applicable to a broad range of substrates and no column chromatographic separation are some salient features of this protocol.

Application of 5570-77-4, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 5570-77-4.

Synthesis, crystal and solution structures of platinacyclic complexes containing eugenol, the main bioactive constituent of Ocimum sanctum L. oil

The dinuclear platinacyclic complex [Pt2Cl2(Eug-1H)(2)] (1) (Eug-1H = deprotonated eugenol) has been synthesized. Reaction of 1 with amines afforded [PtCl(Eug-1H)(pyridine)] (2), [PtCl(Eug-1H)(4-Me-pyridine)] (3), [PtCl(Eug-1H)(piperidine)] (4), [PtCl(Eug-1H)(quinoline)] (5), [PtCl(Eug-1H)(NH3)] (6), [PtCl(Eug-1H)(4-Me-aniline)] (7), [PtCl(Eug-1H)(4-Cl-aniline)] (8), [Pt(Eug-1H)(8-O-quinoline)] (9) and [Pt(Eug-1H)(8-O-2-Me-quinoline)] (10). X-ray diffraction and NMR analysis show that in complexes 1-10 the chelating eugenol ligand is bound with the Pt(II) ion both through the ethylenic double bond of the allyl group and at a benzene carbon atom; in 2-10 the donor N atom of the amine is in the cis-position with respect to the ethylenic double bond. For complexes 2 and 3, two types of relatively strong highly directional intermolecular interactions are observed in the crystal packing: O-H center dot center dot center dot ClPt(II) hydrogen bonds and C-H center dot center dot center dot pi interactions, in 3 further complemented by C-H center dot center dot center dot Cl interactions. The crystal packing of 7 is dominated by dimer formation through O-H center dot center dot center dot O, N-H center dot center dot center dot Cl, C-H center dot center dot center dot Cl and C-H center dot center dot center dot pi interactions. In a d-chloroform solution of 2-5 two types of strong intermolecular interactions were detected: a Cl3C-D center dot center dot center dot ClPt(II) hydrogen bond and Cl2DC-Cl center dot center dot center dot Pt(II) halogen bond. Complex 9 exhibits significant activities on the human cancer cells KB, Hep-G2, MCF-7 and Lu, with IC50 values of 8.7, 10.8, 9.9 and 10.4 mu M respectively. (C) 2018 Elsevier Ltd.

Proline-Catalyzed Asymmetric -Amination in the Synthesis of Bioactive Molecules

The direct -amination of carbonyl compounds using organocatalysts represents a powerful and atom-economical tool for asymmetric C-N bond formation. We describe a complete account of -functionalization of carbonyl compounds, through iterative sequential -aminoxylation/amination using electrophilic O and N sources, as well as sequential -amination/HWE reaction for enantio- and diastereoselective synthesis of both syn – and anti -1,3-aminoalcohols and 1,3-diamines. Additionally this protocol is further extended for the easy construction of alkaloids such as indolizidine, pyrrolizidine, and quinolizidine fused-ring systems just by tuning the chain length of the aldehyde used as a starting material. This methodology provides further scope to extrapolate it for a variety of naturally occurring hydroxylated monocyclic and fused bicyclic pyrrolidine and piperidine based alkaloids such as lentiginosine, epi -lentiginosine, dihydroxypyrrolizidine, (+)-deoxoprosophylline and (-)-deoxoprosopinine alkaloids. Furthermore, we have also uncovered proline-catalyzed anti -selectivity for the synthesis of 1,2-amino alcohols in -amination of aldehyde and one-pot indium-mediated Barbier type allylation of -hydrazino aldehydes to accomplish the total synthesis of clavaminols, sphinganine and spisulosine with reduced number of steps and with high overall yields. 1 Introduction 2 Application in the Total Synthesis of Alkaloids 3 Conclusion
