Abstract:

A mild and efficient oxidative synthesis of isoindolinones has been realized by Rh(Ⅲ)-catalyzed C-H activation of benzamides and[4 + 1] coupling with propargyl alcohols. This coupling system proceeds with broad substrate scope and mild conditions and provides a new approach to access the useful skeleton of γ-lactams with a stereogenic center.
