Chemoselective inhibition of the hydrogenolysis of the MPM protective group for phenolic hydroxy functions using a Pd/C-pyridine catalyst

Article abstract of DOI:10.1016/S0040-4039(96)02309-X

A convenient method for the selective hydrogenation of phenolic benzyl ether, Cbz, benzyl ester, nitro and olefin functions distinguishing from the MPM (4-methoxybenzyl) protective group for the phenolic hydroxy groups was accomplished by the addition of pyridine to the Pd/C-catalyzed reduction system.
