Temperature-Controlled Regioselectivity in the Reductive Cleavage of p-Methoxybenzylidene Acetals
The regioselective ring opening of pyranosidic 4,6-p-methoxybenzylidene acetals with BH(3)/Bu(2)BOTf in THF can be tuned by adjusting the reaction temperature and reagent concentrations. Reductive cleavage at 0 °C resulted in the exclusive formation of 4-O-p-methoxybenzyl (PMB) ethers, whereas react...
