摘要

A flexible enantioselective route to highly functionalized α, β-unsaturated δ-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 ...
