Facile synthesis of sugar lactols via bromine-mediated oxidation of thioglycosides

Synthesis of a variety of sugar lactols (hemiacetals) has been accomplished in moderate to excellent yields by using bromine-mediated oxidation of thioglycosides. It was found that acetonitrile is the optimal solvent for this oxidation reaction. This approach involving bromine as oxidant is superior to that using N-bromosuccinimide (NBS) which produces byproduct succinimide often difficult to separate from the lactol products.

β-glycosides of hydroxyproline via an umpolung approach

Reaction of 1,2-O-dibutylstannylene-3,4-6-tri-O-benzyl-β-D- mannopyranose with Nα-fluorenylmethoxycarbonyl-cis-4- trifluoromethanesulfonyl-oxyproline allyl ester led to formation of a β-mannoside of trans-4-hydroxyproline. Subsequent manipulation of the C
