Dicarboxylic acids, such as malonic acid, have been infrequently used in the form of protected cyclic isopropylidene or benzylidene derivatives, e.g. (15) and (22). The esters are saponified by base and as befits their acetal structures by acids also [56, 57, 67, 126]. Presumably the benzylidene ester may be cleaved by hydrogenolysis. Rather more use has been made of cyclic protecting groups in the case of a-hydroxyacids. Lemieux [68] thus used the ready formation of a neutral... [Pg.199]
