Bis(pentaluorophenyl) sulfite - A new reagent for the synthesis of activated pentafluorophenyl esters of N-protected amino acids

A method was proposed for the preparation of bis(perfluorophenyl) sulfite, an effective new reagent for the synthesis of pentafluorophenyl esters of N-protected amino acids without racemization.

FREE-RADICAL ADDITION TO DI- AND TRIPEPTIDES CONTAINING DEHYDROALANINE RESIDUES

Radical addition, by the alkylmercury halide/sodium borohydride method, to di- and tripeptides containing a dehydroalanine residue proceeds smoothly with good chemical yield, but low diastereoselectivity, to saturated di- and tripeptides.
