Abstract In this research, a wide range of aldoxime derivatives with aromatic and aliphatic substituents were synthesized as precursors to nitrile oxide in cycloaddition reactions. The aldoximes good high yields showed lack diastereoselectivity, confirmed by 1 H NMR measurements. These then utilized 1,3‐dipolar reactions treated dipolarophilic reagents, namely methyl methacrylate (MMA) glycidyl (GMA), produce isoxazoline carboxylate regioselectivity. obtained compounds characterized using...
Abstract This study focuses on the development of environmentally friendly and efficient synthetic routes for novel thiazolo[3,2‐ a ]pyridine‐6‐sulfonamide derivatives with potential antimicrobial properties. Using one‐pot multi‐component approach, these heterocyclic compounds were synthesized both in solution under solvent‐free mechanochemical conditions. Reactions between 1‐(4‐oxothiazolidin‐2‐ylidene)‐ N ‐phenylmethane sulfonamide, malononitrile, aryl aldehydes led to two distinct classes...
Alkylidenepyrrolidines 1, 21, 24 and 26 undergo reactions with nitrile oxides nitrilimines or their precursors to give a range of novel heterocyclic compounds. With alkylidenepyrrolidine ester nitrolic acids products in which the liberated nitrous acid reacts alkylidenepyrrolidine, followed by two cycloadditions adducts 3. In contrast, hydroximoyl chlorides isoxazoles 10, presumably cycloaddition/elimination. hydrazonyl chlorides, simple acylation occurs compounds 17. sulfonyl...
A Pt-modified titania-based catalyst was successfully applied in the synthesis of amines employing several carbonyl containing molecules and nitriles.
A series of ten novel pyridine N-oxide-bearing 5-aminoisoxazoles was efficiently synthesized in moderate yield by reacting 2-(cyanomethyl)pyridine 1-oxide with α-chlorooximes, employing sodium ethoxide as a base. The compounds were verified variety spectra. Subsequently, the inhibitory potency 4c, 4e, 4f, 4h, and 4i against AChE BChE, primary targets Alzheimer's disease, assessed. In silico docking analyses conducted to evaluate interaction MAO-B. Among tested compounds, 4e 4h demonstrated...
Twenty one new thiophene-substituted 1,2,4-oxadiazol-5(4H)-ones, 1,2,4-oxadiazol-5(4H)-thiones, and 1,2,4-oxadiazin-5(6H)-ones were synthesized by the reaction of thiophene-ring substituted amidoximes with ethyl chloroformate, thiophosgene, chloroacetylchloride, respectively. Their structure elucidation was performed means spectral measurements (IR, NMR, MS) physical data.
The recently reported capability of pentachloro-2-nitrobutadiene and some closely related derivatives to allow the synthesis highly substituted acyclic as well five-membered (hetero)cyclic compounds is herein extended pyrimidines with an exceptional substitution pattern. Our novel approach starts from a 1,1-diamino-3,4,4-trichloro-2-nitrobuta-1,3-diene appropriate amidine. Some resulting perfunctionalized were subjected further transformations give promising candidates respect biological,...
A series of thiazolo[3,2-a]pyridin-8-yl-phosphonate derivatives have been obtained by the reaction diethyl (E)-((4-oxothiazolidin-2-ylidene)methyl)phospohonate, malononitrile and two equivalent various aromatic aldehydes in a multicomponent with good yields. The structures new compounds are confirmed spectroscopic methods (IR, 1H, 13C, 31P NMR HRMS). Compound diethyl-(Z)-(5-amino-6-cyano-2-(4-nitrobenzylidene)-7-(4-nitrophenyl)-3-oxo-3,7-dihydro-2H-thiazolo[3,2-a]pyridin -8-yl)phosphonate...
