A series of novel isoxazolyl benzo[f][l,4]oxazepin-3-(2H)-ones (9a-h) have been synthesized by adopting a facile and. simple methodology. The reaction of 3-arnino-5-methylisoxazole (5) with salicylaldehydes (6), followed by reduction with " NaBH4, and in situ chloroacetylation and cyclization with chloroacetyl chloride and triethyl amine affords isoxazolyl benzo[f][l,4]oxazepin-3-(2H)-ones (9a-h). The newly synthesized compounds (7-9) have been characterized by spectral (IR, 1H and 13C NMR, and HRMS) data. The title compounds (9a-h) have been evaluated for their in vitro antimicrobial activity against different bacterial and fungal strains. Compounds 9b, 9f and 9g show excellent antimicrobial activity, when compared to the respective standard drugs.

Synthesis of novel isoxazolyl 1,3,5-benzoxadiazocines 5 has been accomplished by condensation of 3-amino-5-methylisoxazole 1 with salicylaldehydes, followed by reduction, treatment with arylisothio-cyanates, and subsequent ring closure in the presence of
