  Copper-Catalyzed Methylenation Reaction:  Total Synthesis of (+)-Desoxygaliellalactone

  摘要：

  The enantioselective total synthesis of (+)-desoxygaliellalactone was achieved in six steps starting from 4-tert-butyldimethylsilyloxybutanal. This synthesis featured a one-pot copper-catalyzed methylenation-Diels-Alder cyclization. The challenging methylenation of aldehyde 4 was studied under various reaction conditions. Whereas Wittig reaction conditions led to byproducts resulting from decomposition of the sensitive butenolide moiety, the mild copper-catalyzed methylenation reaction produced the desired triene in good yield.
