Utility of N-acyl mesoionic triazolopyridines as acylating reagents was investigated concerning with peptide synthesis. Several dipeptides and N-alkoxycarbonyl amino acids were prepared by use of these reagents.
The picolinoyl group can be used as a convenient protective group for amines in peptide chemistry. Deprotection is performed by electrochemical reduction under mild acidic conditions.

THE CINNAMYLOXYCARBONYL GROUP AS A NEW AMINO-PROTECTING GROUP
A new urethane-type protecting group for amines, cinnamyloxycarbonyl (Coc) group, is described. The cleavage of the Coc group is effectively catalyzed by 5 mol% of [Pd(PPh3)4] in the presence of formic acid, pyridine, and N-hydroxysuccinimide in refluxing THF. The Z- and Boc-protecting groups are not affected under the same reaction conditions.
