ONE-POT SYNTHESIS OF ARYL(HETARYL)THIAZOLYLPHTHALAZINE-1,4-DIONES <i>via</i> MULTICOMPONENT APPROACH

Аннотация

An expeditious one-pot synthesis has been developed to obtain aryl(hetaryl)-substituted thiazolylphthalazine-1,4-diones via multicomponent approach. Reaction of phenacyl bromides with thiosemicarbazide and phthalic anhydride afforded arylthiazolylphthalazine-1,4-diones. Reaction of 3-(2-bromoacetyl)coumarins with thiosemicarbazide and phthalic anhydride afforded hetaryl-containing 2-thiazolylphthalazine-1,4-diones under the same reaction conditions in excellent yields. The structures of all the synthesized compounds were confirmed by their analytical and spectral data.
