L. Xiang et al., STEREOSELECTIVE SYNTHESIS OF ALL INDIVIDUAL ISOMERS OF BETA-METHYL-2',6'-DIMETHYLPHENYLALANINE, Tetrahedron : asymmetry, 6(1), 1995, pp. 83-86
Asymmetric synthesis of all four isomers of beta-methyl-2',6'-dimethyl
phenylalanine was accomplished with complete stereoselectivities and h
igh yields by using the Evans-like auxiliary 4-phenyl-oxazolidinone as
a chiral auxiliary and as a chiral resolution reagent.
