Benzotriazol-1-yl alkyl carbonate, a new convenient and inexpensive coupling agent to prepare an active ester for the synthesis of amide

Benzotriazol-1-yl alkyl carbonate 1 has been found to be a new convenient and inexpensive coupling agent to prepare an active ester 2 for the synthesis of an amide 3 in good yield and with high purity.

A Synthetic Approach to Peptides of o- and p-Aminobenzoic Acids

Active esters of o- and p-aminobenzoic acids served as coupling components syntheses without concomitant protection of the relatively inert aromatic amino group.The products were then treated directly with benzyloxycarbonylamino acid symmetrical anhydrides to form higher peptide derivatives.An analogue of leucine-enkephalin with the glycyglycyl segment replaced by a p-aminobenzoyl residue has been synthesized by this route.
