;1991, 2(2): 115-118.
-
A series of α-amino acids are obtained in 72-96% optical yields by alkylation of the ketimine derived from (+)-2-hydroxy-pinan-3-one and (-)-menthyl glycinate followed by hydrolysis of the alkylated intermediates with mineral acid. The double asymmetric induction are explained by the transition model of lithium enolate.
