摘要：

Heterocyclic P-substituted alanine derivatives such as beta-(pyrazol-1-yl) and beta-(1,2,4-triazol-1-yl)-alanine are synthesized in high yields by a Michael addition of heterocyclic nucleophiles to N,N-bis(tert-butyloxycarbonyl)dehydroalanine methyl ester, using mild reaction conditions and simple work-up procedures.
