Optically active syn- or anti-β-substituted-α-amino acid derivatives are prepared in 94 to ≥99% ee and 66-98% ds by reaction of the Schiff base acetate of glycine tert-butyl ester with chiral, nonracemic B-alkyl-9-BBN derivatives in the presence of the Cinchona alkaloid, cinchonidine (CdOH) or cinchonine (CnOH), base, and lithium chloride.
