Deprotonation of peptides in the presence of zinc chloride gives rise to highly reactive nucleophiles that can be subjected to palladium-catalyzed allylicalkylation reactions. Excellent diastereoselectivities are obtained that are nearly independent of the allylic substrate used. By using this protocol, highly functionalized side chains can also be incorporated in excellent yields and selectivities

Abstract The development of the tetrabenzylglucosyloxycarbonyl (BGloc)-protectinggroup as an enzymatically removable urethane protecting function for peptide synthesis is described. BGloc-protected amino acids are readily synthesized by conversion of amino acid allyl esters into the respective isocyanates, subsequent treatment with 2,3,4,6-tetrabenzylglucose and C -terminal allyl ester cleavage.
