Starting from ethyl acetoacetate and substituted heterocyclic aldehyde, a series of new 4-methyl-2-heterocyclic-2,3-dihydro-benzo[f]-1,5-thiazepine-3-carboxylic acid ethyl esters (2a2l) were synthesized through 2-step reactions, and of which five compounds were reduced. The structures of the compounds were characterized by 1H NMR, IR, MS, elemental analysis and X-ray diffraction study. The crystal of compound 2a belongs to triclinic system, space group P-1. The antibacterical activities of the new compounds against B. subtilis, C. albicans and C. neoformans were evaluated by filter paper approach, and the results indicated that most of them showed antibacterical activities, especially the compound 2a prominent.

Key words: 1,5-benzothiazepine, heterocyclic, reduction, crystal structure, antibacterical activity
