The organocatalytic trichlorosilanereduction system has been successfully utilized to develop a multi‐step tandem approach for the easy preparation of chiral 2‐methyl‐3‐alkylindolines starting from simple 2‐methylindoles and aldehydes. A broad range of chiral 2‐methyl‐3‐alkylindoline products was obtained with high yields and enantioselectivities and excellent stereoselectivities by this approach
