A new approach to highly functionalized quinolines is proposed.

This approach is based on the electrophilic recyclization of 2-[2-(acylamino)benzyl]furans

under the Bischler-Napieralski reaction conditions.

furans - ring opening - ring closure - fused-ring

systems - quinolines - Bischler-Napieralski

reaction
