A scalable and environment-friendly one-pot two-component synthesis of chiral -protected amino acid substituted 1,2,4-oxadiazoles from hydroxyl amidine and ()-2-(2,2,2-trifluoroacetamido)propanoic 2,2,2-trifluoroacetic anhydride is described. This operationally simple methodology affords an efficient and convenient solution to synthesize chiral -protected amino acids under catalyst-free conditions. All the synthesized compounds were screened for their antibacterial activity towards six human pathogenic bacterial species, among which, 4al exhibited a significant efficacy against with the MIC value of 0.

A facile and convenient metal-free direct oxidative amination of acetonitrile followed by cyclization with aroyl hydrazide for synthesizing oxadiazoles has been investigated. Disubstituted 1,3,4-oxadiazoles were obtained at 50-82% yields using readily available acetonitrile as both reagent and solvent. In addition, the reaction of aroyl hydrazides with thioacetamide and cyanothioacetamide afforded 5-methyl-2-aryl-1,3,4-thiadiazoles and 2-aryl-1,3,4-oxadiazole-2-acetonitriles as the main products, respectively.

Objective The study's goal was to come up with and make a new group of 1,3,4-oxadiazole derivatives (3a-3e) and test how well they could kill (Mtb) H37Rv strain. Additionally, molecular docking and pharmacokinetic properties were analyzed using computational software to identify potential inhibitors, followed by in vitro antimycobacterial assays. Methods A group of 1,3,4-oxadiazoles was prepared by reacting acyl hydrazides with alanine, an N-protected α-amino acid, and a small amount of POCl.
