Starting from substituted heterocyclic aldehyde and acetylacetone, a series of new 4-methyl-3-acetyl-2-heterocyc-lic-2H,3H-benzo[f]-1,5-thiazepines 3a3l were synthesized through 3-step reactions. The structures of the new products were confirmed by 1H NMR, IR, MS and elemental analysis, and the imine-enamine tautomerism of the target compouds was investigated by means of 1H NMR spectroscopy. Their antifungal activities were evaluated, and the results provides the inspiration for structure-activity reationship of the benzothiazepines. Meanwhile, the structure of the main by-products of 3h was identified, and the possible mechanism of the by-products was proposed.

Key words: 1,5-benzothiazepine, heterocyclic, side reaction, antifungal activity
