  Enantioselective Syntheses of Isoaltholactone, 3-epi-Altholactone, and 5-Hydroxygoniothalamin

  摘要：

  GRAPHICSA flexible enantioselective route to highly functionalized alpha,beta-unsaturated delta-lactones has allowed for the syntheses of the styryllactones: isoaltholactone, 3-epi-altholactone, and 5-hydroxygoniothalamin in 10%, 5%, and 13% overall yields from furfural, respectively. This approach derives its asymmetry by applying the Sharpless catalytic asymmetric dihydroxylation to vinylfuran. The resulting diols are produced in high enantioexcess and can be stereoselectively transformed into alpha,beta-unsaturated delta-lactones via a short highly diastereoselective oxidation and reduction sequence.

  Sharpless catalytic asymmetric dihydroxylation to vinylfuran. The resulting diols are produced in high enantioexcess and can be stereoselectively transformed into α,β-unsaturated-δ-lactones via a short highly diastereoselective oxidation and reduction sequence. Wittig olefination or Julia olefination reactions were used to introduce the phenyl group side chain either cis or trans selectively and these
