Abstract
An intermediate,1-methoxy-1-oxo-3-phenylpropan-2-aminium chloride( 1),was prepared by methyl-esterification of L-phenylalanine. Four L-phenylalanine Derivatives in yield of 90. 7% ~94. 2 were synthesized by activation of 1 via triphosgene,using triethylamine as the acid acceptor,and then reacted with primary amine. The structures were confirmed by1 H NMR,MS and X-ray diffraction.
