Abstract
A few benzothiazepinyl chromones (II & IV) were prepared by the reaction of 2-amino benzenethiol with new types of chromonyl chalcones (I & III). One representative compound (IVb) was cleaved with hydrazine hydrate and with hydroxylamine hydrochloride to afford pyrazole (V) and isoxazole (VI) derivatives. The structures of these compounds were confirmed by their analytical and spectral analysis. Some of the above compounds were screened for their anti-microbial activity.
