Synthesis of Imidazo[2,3‐a]isoquinoline and Imidazo[3,2‐a]quinoline Derivatives with Ynones, Isoquinolines and Quinolines

Abstract A mild dearomatization/annulation cascade sequence of isoquinolines and quinolines with ynones has been developed. Highly functionalized imidazo[2,3‐ a ]isoquinoline and imidazo[3,2‐ a ]quinoline derivatives could be prepared directly in moderate to excellent yields.
