An efficient stereoselective synthesis of stypodiol and epistypodiol

An efficient synthesis of stypodiol (1) and its epimer at C-14, epistypodiol (2), was accomplished starting from (S)-(+)-carvone (7). The synthesis of both epimeric compounds proceeds through common intermediates using an IMDA reaction, a sonochemical Barbier reaction, and an acid- catalyzed quinol-tertiary alcohol cyclization as key synthetic steps.
