Abstract

Synthesis of substituted-1,3,2- oxazaphospholo 1- amines/oxides was accomplished via two-step process. It involves the preparation of mono chloride intermediate (2) and its subsequent reaction with various substituted aromatic amines/ heterocyclic amines in dryTHF in the presence of triethylamine at 50-55 ºC. These compounds were characterized by IR, 1H, 13C, 31P NMR andMS data.All the title compounds were found to exhibitmoderate antimicrobial activity.
