Phosphine-Catalyzed α-Umpolung–Aldol Reaction for the Synthesis of Benzo[b]azapin-3-ones
A novel phosphine-catalyzed intermolecular cyclization between 2-sulfonamidobenzaldehyes and ynones is reported. This methodology serves as a conduit for the construction of benzo[b]azepin-3-ones in good to excellent yields under mild conditions. The resulting 2-benzylidene moieties are formed exclu...
