✦ Synopsis


A benzophenone imine of N-1 protected ct-aminomethyltetrazoles was found to undergo alkylation with organic halide:; in good yields. Deprotection afforded tetrazole analogs of a-amino acids.

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 a
