摘要：

A new class of thiazole-fused diazepinones has been synthesized by the application of intramolecular hydrazonolysis, wherein 2-arylamino-4-coumarinyl5-formyl thiazoles were treated with hydrazine hydrate in refluxing ethanol to yield the rearranged products via an interesting ring-opening and cyclization process.
