Ir(iii)-catalyzed selective C–H acylmethylation and dicarbonylation of indolizines with β-ketosulfoxonium ylides

Herein, we report an Ir( iii )-catalyzed regioselective C–H acylmethylation of indolizines with β-ketosulfoxonium ylides, enabling the efficient synthesis of C3-functionalized indolizine derivatives.
