Enantioselective alkynylation of C(sp3)Hbonds adjacent to a nitrogen atom has been achieved using only chiral p‐tolyl tert‐butyldimethylsilylethynyl sulfoximine and benzophenone under photo‐irradiation conditions. A two‐carbon alkyne unit was chemo‐ and enantioselectively transferred at the nitrogen‐substituted methylene to produce the optically active propargylic amines of various structures. Remarkably
