Carbene insertion into acyl C-H bonds: Rh(III)-catalyzed cross-coupling of 2-aminobenzaldehydes with conjugated enynones

A rhodium-catalyzed directed acyl C-H bonds carbene insertion reaction of 2-aminobenzaldehydes with conjugated enynones has been realized, affording a series of a-furyl ketone derivatives in moderate to good yields with good functional group tolerance. Carbene migratory insertion is proposed as the key step in this transformation. (C) 2021 Elsevier Ltd. All rights reserved.
