Abstract
Optically active a-amino ketones of known configuration (D-) can be prepared by virtue of the Bowman ketone synthesis starting with optically active, natural a-amino acids as acylating components. By reduction of a-amino ketones and of their oximes with lithium aluminum ,hydride the hydroxy and the second amino group were induced asymmetrically yielding in both cases predominantly the erythro epimers of corresponding a- amino alcohols and a-diamines. This is in agreement with Cram's rule of the steric control of the asymmetric induction.
