Broadening the Chemical Scope of Laccases: Selective Deprotection of N-Benzyl Groups

Abstract

Laccase from Trametes versicolor together with TEMPO has been found as a very efficient system to deprotect Nbenzylated primary amines, differing from previously described methods since it uses oxygen as mild oxidant in aqueous medium. Chemoselective removal of the benzyl group was achieved with excellent yields when secondary amine and alcohol moieties were also present
