An Asymmetric Strecker Synthesis of (R)-(+)-2-Methyl-3-Phenylalanine: An Efficient Preparation

Abstract
A convenient four-step asymmetric Strecker synthesis, utilizing (S)-(-)-1-phenylethylamine as the chiral auxiliary reagent, is described for the preparation of (R)-(+)-2-methyl-3-phenylalanine in >98% enantiomeric excess.
