Stereoselective synthesis of substituted exo-glycals from 1-exo-methylene pyranoses
TL;DR: Halo-exo-glycals of the gluco-, manno- and galacto- series, readily prepared by reaction of 1-ex-methylene pyranoses with iodonium dicollidinium triflate, undergo Suzuki or B-alkyl Suzuki cross-coupling reactions with boronic acids or alkyl boranes to yield functionalized exo- glycals.
Journal ArticleDOI
Serial Radical Cyclization of Pyranose-Derived Dienes in the Stereocontrolled Synthesis of Densely Functionalized Cyclohexanes. A Route to Woodward's Reserpine Precursor
TL;DR: In this paper, a readily prepared hexopyranose derivative having unsaturations on-template at C-2 and off-template in a tricyclic cage was shown to have all stereocenters in an optically pure form of Woodward's densely functionalized carbocyclic precursor.
Journal ArticleDOI
Thioglycoside and trichloroacetimidate donors in regioselective glycosidations. Comparison with n-pentenyl glycosides
TL;DR: Thioglycoside and trichloacetimidate donors show the same regiopreferences as NPG analogs for selective glycosidation of an altroside diol, indicating that the selectivity may be general for donors.
Journal ArticleDOI

TL;DR: Two complementary one-pot, three component synthetic strategies based on copper(I)-catalyzed azide–alkyne cycloadditions (CuAAC) have been developed, which allow the efficient assembly of glycosyl-derived alkynes or azides with highly fluorescent boron–dipyrromethene (BODIPY) cores containing azido or alkyne moieties, respectively.
Journal ArticleDOI
Six- versus five-membered ring formation in radical cyclization of 1-vinyl-5-methyl-5-hexenyl radicals
TL;DR: In this paper, 6-endo-trig ring closure and rearrangement of intermediate methylenecyclopentyl radicals obtained by 5- exo -trig cyclization are discussed.
