Description
Summary: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 0.19 μg mL .
