9-Fluorenylmethyl Pentafluorophenyl Carbonate as a Useful Reagent for the Preparation ofN-9-Fluorenylmethyloxycarbonylamino Acids and their Pentafluorophenyl Esters

Abstract

9-Fluorenylmethyl pentafluorophenyl carbonate is a useful reagent for the efficient, side reaction-free introduction of N-9-fluorenylmethyloxycarbonyl protecting group into amino acids and for the subsequent preparation of their pentafluorophenyl esters. Some new compounds of both types are described.
