[structure] An enantioselectivesynthesis of three diastereoisomers of the C-arylglycoside tricyclic spiroketal nucleus of the papulacandins has been achieved, in which the initial asymmetry was introduced via a Sharpless dihydroxylation of substituted 5-aryl-2-vinylfurans. A selective oxidation-reduction sequence converted the mannose isomer into the glucose isomer. This sequence can conveniently
