A green way to amino acids: α-Tetrasubstituted α-amino acid derivatives are formed in high yield and enantioselectivity by using a Rh-catalyzed enantioselective alkynylation of α-ketiminoesters. This reaction, which involves a proton transfer and can be conducted at room temperature, has high substrate scope (see scheme; Cbz=benzyloxycarbonyl, Fmoc=9-fluorenylmethyloxycarbonyl).
