A new one-pot method was developed for creating chiral -protected amino acid substituted 1,2,4-oxadiazoles using hydroxyl amidine and a specific anhydride, promoting sustainability.
This simple process does not require catalysts, making it a more efficient way to synthesize these amino acids.
The newly synthesized compounds were tested for antibacterial activity, with one compound (4al) showing notable effectiveness against certain harmful bacteria at a minimal inhibitory concentration of 0.19 μg/mL.
