Abstract
Abstract In order to establish a mild protection method for hydroxy functions with a MPM (4-methoxybenzyl) group, various types of hydroxy compounds were treated with MPM trichloroacetimidate in the presence of an acid catalyst. A catalytic amount (0.3 mol %) of trifluoromethanesulfonic acid was most effective and the reaction was completed within 40 min at room temperature even for highly sterically hindered hydroxy groups.
