Abstract
Removal of some commonly used protecting groups in peptide synthesis by catalytic transfer hydrogenation employing hydrazinium monoformate and 10%Pd on carbon is described. This method is equally competitive with other methods in deblocking most of the commonly used protecting groups in peptide synthesis. tert-Butyl derived and base labile protecting groups were completely stable under these conditions. This is more effective than hydrazine or formic acid.
Keywords: catalytic transfer hydrogenation, hydrazinium monoformate, new hydrogen donor, deprotection
