Abstract
A C–H alkylation/nucleophilic addition manifold with synthetically useful aryl oximes and pyrazoles was realized by rhodium(III) catalysis under remarkably mild reaction conditions. Valuable β‐acyl substituted arylbutanoates were obtained in moderate to good yields. This strategy is characterized by excellent atom‐ and step‐economy, high chemo‐ and site‐selectivity, a broad substrate scope, and a wide functional group tolerance.
