Effective chemoselective deprotection of 3,4-dimethoxybenzyl ( 3,4DMB) ethers in the presence of benzyl and p-methoxybenzyl (PMB) ethers by phenyliodine(III) bis(trifluoroacetate) (PIFA)
In this Letter, a selective deprotection of the alcohol protecting 3,4-dimethoxybenzyl (3,4DMB) group is described. The hypervalent iodine(III) reagent phenyliodine bis(trifluoroacetate) (PIFA) is found to be an efficient reagent for the chemos
