Direct enantioselective allylic C—H functionalization has emerged as a powerful strategy for the asymmetric synthesis of highly valuable chiral products. Herein, a Rh(III)-catalyzed enantioselective allylic C—H alkylation of unactivated alkenes with α-diazo carbonyl compounds is described, enabling direct access to chiral products with high efficiency (up to 77% yield, 92% ee, and >10∶1 B/L (branched/linear) selectivity). This atom-and step-economical protocol directly converts simple, unactivated substrates into valuable enantioenriched products under mild conditions, providing an efficient catalytic system for asymmetric allylic C—H functionalization.

Key words: C—H bond activation, asymmetric allylic alkylation, Rh(Ⅲ)-catalysis, diazo compound
