Abstract: The new approach for the asymmetric synthesis of a-amino acids from a-keto acids which is described in the foregoing paper has been extended with the development of a highly selective stereochemical system. The levorotatory chiral reagent 14 has been prepared by stereospecific synthesis and resolution (Chart I) and has been applied to the asymmetric synthesis of a number of a-amino acids (Chart IV). The D-amino acids alanine, ...
