摘要：

A new one-pot procedure for the preparation of pentafluorophenyl and 3,4-dihydro-4-oxo-1,2,3-benzotriazine-3-yl esters of N-alpha-9-fluorenylmethyloxycarbonyl amino acids bearing no side chain protecting groups is described. The method gives the desired activated esters in high yield and purity without use of the highly allergenic DCC.
