  Acyclic diastereocontrol and asymmetric transmission via anionic oxy-Cope rearrangement: a synthetic application of sequential [2,3]Wittig-oxy-Cope rearrangements

  摘要：

  The anionic oxy-Cope rearrangements of acyclic 1,5-dien-3-ols with the 3,4-erythro configuration established by the [2,3]Wittig rearrangement are shown to provide a useful level of diastereoselection and asymmetric transmission in the context of a formal asymmetric synthesis of an insect pheromone.

• Butenolide Synthesis by Molybdenum-Mediated Hetero-Pauson−Khand Reaction of Alkynyl Aldehydes

  The highly reactive complex Mo(CO)(3)(DMF)(3) promotes the CO gas-free cyclocarbonylation of 1,5- and 1,6-alkynyl aldehydes under very mild reaction conditions to provide fused butenolides in good yields. This novel Mo-mediated hetero-Pauson-Khand reaction is very general with regard to the substitution at the alkyne terminus and tether (18 tested cases). Using readily available chiral alkynyl aldehydes, this procedure has been applied to the enantio- and stereoselective synthesis of highly substituted bicyclic butenolides, including an intermediate in natural product synthesis.

  The anionic oxy-Cope rearrangements of acyclic 1,5-dien-3-ols, when their stereochemistries are properly designated. are shown to proceed with a high level of diastereoselection and asymmetric transmission. The utility of the acyclic oxy-Cope variants is demonstrated by the stereocontrolled synthesis of the key precursors of (+)-faranal (insect pheromone) and (-)-antirhine (Corynanthe-type indole alkaloid).
