PYRANOSIDIC HOMOLOGATION: PART II: EXTENDING THE CARBOHYDRATE TEMPLATE VIA VICINAL (SECONDARY) HYDROXYLS

The oxyrane ring of the dianhydro sugar (3b) is opened regioselectively by the dianion (4b), and reaction of the derived allylic alcohol (7b) with trifluoroacetic acid gives the oxa-cis-decalin (8b), which can be epoxidised selectively from the endo or ex
