“…The few known examples include the removal of 3,4-O-isopropyliden in the presence of 1,2- O -isopropylidene ketal in diacetone galactose with dilute hydrochloric acid in acetone, 118 and with concentrated nitric acid in ethyl acetate. 34 Recently, Zhang et al developed the removal of 1,2-O-isopropylidene in the presence of 3,4- O -isopropylidene ketal in diacetone galactose. Di- O -acetate 81 was obtained in 78% yield from the di- O -isopropylidene protected pyranose 80 in the presence of TFA and acetic anhydride (Scheme 15).…”
