  Total synthesis of (–)-solavetivone using enantioselective copper-catalysed conjugate addition of Me₃Al to a cyclohexa-2,5-dienone intermediate

  摘要：

  By applying a new enantioselective Cu-catalysed conjugate addition of Me(3)Al, (-)-solavetivone 1 is synthesized stereoselectively from cyclohexa-2,5-dienone 4, prepared from a chiral compound 6 using a regioselective Hg-II-mediated cyclopropyl ring-opening, subsequent Pd-II-mediated spiroannulation of 7, and a stereoselective Pd-0-catalysed hydrogenation of an allylic formate 5 as key reactions.
