✦ Synopsis

A new general method of resolution of &_-amino acids via their Schiff bases with 2-hydroxy pinan-3-ones is described. It complements the asymmetric synthesis of o(-disubstituted amino acids by alkylation of the Schiff bases.

Asymmetric synthesis methods1'2 seldom give enantiomerically pure amino acids.

Thus, a final resolution procedure is almost always necessary, especially if the compounds
