[摘要]：A series of novel methylene bis-isoxazolo[4,5-b]azepines have been synthesized by reaction of 3,5-dimethyl-4-nitroisoxazole 6 with an appropriate methylene bis-chalcones 7 to obtain various Michael adducts 8a-i, which on treatment with SnCl(2)-MeOH underwent reductive cyclization to afford the title compounds 9a-i. Structure of these compounds were established on the basis of IR, (1)H NMR, (13)C NMR and mass spectral data. The title compounds 9a-i were evaluated for their in vitro antimicrobial and anticancer activities. Compounds 9h and 9i exhibited potent antimicrobial and anticancer activities as that of standard drugs. (C) 2012 Elsevier Masson SAS. All rights reserved.
