Article abstract of DOI:10.1055/s-1988-27612

N-Benzyloxycarbonyl amino acid chlorides and α-benzyloxycarbonyloxy carboxylic acid chlorides are readily available by treating the corresponding carboxylic acids with 1-chloro-N,N,2-trimethyl-1-propen-1-amine.They can be immediately reacted with O-, N- and C-nucleophiles to afford peptides, ketones and esters.
