Eleuthesides and Their Analogs: IV.* Synthesis of(1R,5R,6S)-6-(1,3-Dithian-2-yl)-1-(2-hydroxyethyl)-5-methyl- cyclohex-3-ene and Its O-tert-Butyldimethylsilyl Derivative

摘要

Two schemes for the preparation of chiral alcohols as key synthons for the synthesis of eleutheside analog at the A ring have been developed on the basis of the Diels-Alder adduct of levoglucosenone with piperylene.
