An achiral Lewis acid enables chiral palladium complex-catalyzed cascade C−H functionalization/asymmetric allylation reaction of aryl α-diazoamides and allenes to give synthetically useful chiral 3,3-disubstituted oxindole derivatives in enhanced yield and enantioselectivity (up to 93 % ee).

A novel protocol for the preparation of various 3-alkylideneoxindoles via a silver-catalyzed aromatic CâH functionalization has been developed. The process is simple, environmentally conscious, and avoids the use of abundant bases, oxidants, or other additives.
