Herein, γ-lactam derivatives are obtained in high yield via highly regioselectiveintramolecular Csp3–H insertion reactions of α-diazoacetamides catalyzed by a rac-Ru(II)–Pheox complex. The catalytic system is applicable to a wide range of diazoacetamides under mild conditions to produce the corresponding γ-lactams.
