Enantioselective Michael addition of 3-ethyl carboxylate substituted pyrazolones to 5-alkenyl thiazolones catalyzed by squaramide organocatalyst

Asymmetric Michael addition between 3-ethyl carboxylate substituted pyrazolones and 5-alkenylthiazolones catalyzed by a series of chiral bifunctional hydrogen bonding organocatalysts was investigated. Good yields (up to 96%) and excellent enantioselectivities (up to 99% ee) were achieved by using a squar-amide containing piperidine group derived from (1S, 2S)-cyclohexanediamine. This strategy provides facile access to a diverse library of thiazole-pyrazolone derivatives with potential bioactivity. (C) 2018 Elsevier Ltd. All rights reserved.

Absolute Configuration of Solenopsis Piperidines is a Tool to Classify Fire Ants (Formicidae: Myrmicinae)

Piperidine alkaloids are predominant in ant venom glands of S. invicta and S. saevissima. These ants are broadly sympatric in Southeastern Brazil, and potentially diagnostic compounds could assist in ant identification. We determined the absolute configuration of 2,6-dialkyl-piperidines of S. invicta and S. saevissima workers and used these data to group Southeastern Brazil species. The monitoring of venom samples by chiral gas chromatography coupled to a flame ionization detector (GC-FID) revealed that S. saevissima produces the four stereoisomers of 2-methyl-6-undecylpiperidines, 2-methyl-6-tridecyl-piperidines and 2-methyl-6-tridecenyl-piperidines, while S. invicta venom consisted primarily of a single enantiomer cis and trans from each piperidine alkaloid. Our findings showed that the absolute configuration of piperidine alkaloids of fire ant venom may be a potential chemical tool to distinguish S. invicta and S. saevissima sympatric species in Southeastern Brazil.

Cinnamoyl-N-Acylhydrazone-Donepezil Hybrids: Synthesis and Evaluation of Novel Multifunctional Ligands Against Neurodegenerative Diseases

A new series of ten multifunctional Cinnamoyl-N-acylhydrazone-donepezil hybrids was synthesized and evaluated as multifunctional ligands against neurodegenerative diseases. The molecular hybridization approach was based on the combination of 1-benzyl-4-piperidine fragment from the anti-Alzheimer AChE inhibitor donepezil (1) and the cinnamoyl subunit from curcumin (2), a natural product with remarkable antioxidant, neuroprotective and anti-inflammatory properties, using a N-acylhydrazone fragment as a spacer subunit. Compounds 4a and 4d showed moderate inhibitory activity towards AChE with IC50 values of 13.04 and 9.1 mu M, respectively. In addition, compound 4a and 4d showed a similar predicted binding mode to that observed for donepezil in the molecular docking studies. On the other hand, compounds 4a and 4c exhibited significant radical scavenging activity, showing the best effects on the DPPH test and also exhibited a significant protective neuronal cell viability exposed to t-BuOOH and against 6-OHDA insult to prevent the oxidative stress in Parkinson’s disease. Similarly, compound 4c was capable to prevent the ROS formation, with indirect antioxidant activity increasing intracellular GSH levels and the ability to counteract the neurotoxicity induced by both OA beta 1-42 and 3-NP. In addition, ADMET in silico prediction indicated that both compounds 4a and 4c did not show relevant toxic effects. Due to their above-mentioned biological properties, compounds 4a and 4c could be explored as lead compounds in search of more effective and low toxic small molecules with multiple neuroprotective effects for neurodegenerative diseases.

Asymmetric Synthesis of 2,3,6-Trisubstituted Piperidines via Baylis-Hillman Adducts and Lithium Amide through Domino Reaction

A convenient asymmetric synthesis of methyl (2S,3S,6R)-6-(4-fluorophenyl)-2-(4-hydroxyphenyl)-piperidine-3-carboxylate is described, starting from Baylis-Hillman adducts. The route involves a domino process: allylic acetate rearrangement, stereoselective IrelandClaisen rearrangement and asymmetric Michael addition, which provides a.-amino acid derivative with full stereochemical control. A subsequent chemoselective transformation of one of the side-chain groups allows an effective cyclization leading to biologically interesting polysubstituted piperidines in which the 2,6-aryl groups could be attached sequentially.

Novel thermal radical initiators based on a triazene moiety for radical polymerization

In this study, we designed and synthesized novel thermal radical initiators of BTAP (1-phenyl-3,3-dipropyltriazene), BTACP (1-(phenyldiazenyl)pyrrolidine), BTACH (1-(phenyldiazenyl)piperidine), and BTACH7 (1-(phenyldiazenyl)azepane) based on a triazene moiety to provide a thermal initiator for radical polymerization. The synthetic method is valuable due to the simplicity. In addition, the synthesized thermal initiator did not affect the color of the polymer. Among the four initiators, the polymerization time for the BTACH of the 6-membered ring decreased by 67%, as opposed to the polymerization time without initiator. Conversion after polymerization was over 92%. DSC experiments also showed that the initiator with hexagonal rings had the lowest peak polymerization temperature of 160 degrees C. Our study suggests a promising new initiator system that is effective for radical polymerization. (C) 2018 The Korean Society of industrial and Engineering Chemistry. Published by Elsevier B.V.

Facile synthesis and characterization of novel benzo-fused macrocyclic dicarbonitriles and pyrazolo-fused macrocycles containing thiazole subunits

Novel bis[2-(thiazol-2-yl)acetonitriles], linked to aliphatic cores via ethers, were prepared by the reaction of the appropriate bis(2-bromoethan-1-one) with 2-cyanothioacetamide in dioxane at reflux. Bis[2-(thiazol-2-yl)acetonitriles] were taken as key intermediates for the preparation of a new class of macrocyclic dicarbonitriles bearing two thiazole units and containing two O-2-donor sets and fused with two benzene units. The target macrocyclic dicarbonitriles were prepared by the cyclocondensation of bis[2-(thiazol-2-yl)acetonitriles] with the appropriate bis(aldehydes) in N,N-dimethylformamide in the presence of piperidine at reflux. Moreover, a new class of pyrazolo-fused macrocycles containing thiazole subunits were prepared by the reaction of macrocyclic dicarbonitriles with hydrazine hydrate in ethanol at reflux. The structures of the novel macrocycles bearing thiazole subunits were elucidated by considering their elemental analyses as well as their IR, mass, H-1 NMR and C-13 NMR spectral data.

Dual reactivity of B(C6F5)(3) enables the silylative cascade conversion of N-aryl piperidines to sila-N-heterocycles: DFT calculations

The first catalytic access to bridged sila-N-heterocycles from piperidines via cascade sp(3) and sp(2) C-Si bond formation all mediated by a single catalyst B(C6F5)(3) (A) has been recently developed by Park and Chang. Described herein is a theoretical study of the B(C6F5)(3)-catalyzed silylative cascade conversion of N-aryl piperidines (H) to afford polycyclic azasilaheterocycles with a strong emphasis on the dual reactivity of B(C6F5)(3). The DFT calculations show that the catalyzed reaction involves three steps of the cascade reaction: (i) the formation of tetrahydropyridine (I) upon dehydrogenation of the piperidine; (ii) beta -selective hydrosilylation of tetrahydropyridine; (iii) an intramolecular sila-Friedel-Crafts reaction to form a bridged sp(2) C-Si bond. The N-silyl piperidinium borohydride (A ‘) turns out to be the thermodynamically favored, resting species of the overall reaction, which is consistent with the observation of a species such as A ‘ during borane catalysis. The DFT calculations suggest that the beta -selective hydrosilylation of I is the rate-determining step in the entire catalytic cycle, while the liberated I reacts with B(C6F5)(3) to form a zwitterion consisting of iminium and borate units (O). The calculated sila-Friedel-Crafts reactions of a range of presupposed silylated (cyclic)aza intermediates imply the importance of structural integrity on the piperidinyl unit of substrates.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 143900-44-1, you can contact me at any time and look forward to more communication. HPLC of Formula: C10H19NO3.
