A Route to Highly Functionalized Stereospecific trans -Aminated Aurones from 3-Bromoflavones with Aniline and N -Phenylurea via a Domino Aza-Michael Ring Opening and Cyclization Reactions

A facile cascade reaction is reported via aza-Michael addition, ring opening, and cyclization between 3-bromoflavone and aniline derivatives or N -phenylurea in the presence of KO t -Bu and CuI in DMF under mild reaction conditions. Products were obtained as stereospecific trans -aminated aurones in good to excellent yields (61-83%). Our protocol is operationally successful with ease, avoids the requirement of additives and ligands, and offers broad substrate scope.
