Alkylations of the Side-chain Nucleophiles of Cysteine, Methionine, Histidine, and Lysine Derivatives with Allyl Bromide, 1-Bromo-2-butyne, and 2-Bromoacetophenone

Abstract

Comparative studies on the reactions of cysteine, methionine, histidine, and lysine derivatives with allyl bromide, 1-bromo-2-butyne, and 2-bromoacetophenone have been carried out in connection with an evaluation of the potential of reagents incorporating ethylenic and acetylenic functions for protein modification.
