Abstract
Despite significant progress in the area of enaminone vinyl CH functionalization, approaches for the direct synthesis of phenoxyl enaminone molecules remain a challenge. Here we describe a highly efficient 1,3‑Dibromo 5,5-dimethylhydantoin (DBDMH)-promoted cross-coupling reaction between enaminones and phenols. This method provides straightforward access to a wide range of polyfunctionalized aminophenoxyalkenes under mild conditions. The main advantageous features of this method includes a wide substrate scope and good functional group tolerance, operational simplicity, and easily available starting materials.
