Substituent-dependent asymmetric synthesis of L-threo- and L-erythro-[2,3-2H2]phenylalanine from chiral (Z)-dehydrophenylalanine

Abstract

A stereo-divergent synthesis of L-threo- and L-erythro-[2,3-²H₂]-phenylalanine by a catalytic deuteriation of (Z)-dehydrophenylalanine included in a chiral diketopiperazine ring is accomplished simply by changing the substituents on the nitrogen atoms in the diketopiperazine ring.
