Asymmetric catalytic hydrogenations of three kinds of chiralpyruvamides were carried out using palladium on charcoal as a catalyst to give lactamides with diastereomeric ratios ranging from 76:24 to 98:2.

Oximes and benzylimino derivatives of chiralpyruvamides were hydrogenated over palladium hydroxide on charcoal in several solvents. Oximes of pyruvamides containing (R)-α-ethylbenzylamine as a chiral source gave (S)-alanine in excess (up to 70% e.e.) through the hydrolyses of the hydrogenated products.
