✦ Synopsis

Abstract

A novel synthesis of substituted thieno[3,2‐c]azepinones is described. This new approach uses 5,5‐dimethyl‐1,3‐cyclohexanedione (dimedone) as the starting material. Oxime intermediates are obtained in three steps from the aforementioned diketone. Using these intermediates, the title compounds are synthesized in moderate yields.
