An asymmetric synthesis of alpha-amino acids with novel beta-branched side chains has been implemented. The syntheses feature a p-toluenesulfinylimine induced chiral Strecker approach and were found to be applicable to the introduction of both aliphatic and aromatic beta-branched sidechains for preparation of previously unknown alpha-amino acids.
