Abstract
In producing optically-active amino acid benzyl esters by reacting optically-active amino acids with benzyl alcohols, hydrazines are present in the reaction system, or the compounds are reacted in the absence of oxygen, or the compounds are reacted in the absence of oxygen while hydrazines are present in the reaction system. The processes are simple and give optically-active amino acid benzyl esters of high optical purity.
