%X The o-nitrophenylthio derivative of 2-methylalanine served as the precursor of several new ester hydrochlorides, which have been investigated as intermediates for the synthesis of peptides containing this amino acid. Particular consideration is given to the effect of the steric hindrance associated with 2-methylalanine. Synthesis of a 2- methylalanyl analogue of the opiate agonist leucine-enkephalin is described.
