  名称：

  Cleavage of unsaturated .alpha.-ketols to .omega.-oxo-.alpha.,.beta.-unsaturated acids

  摘要：

  Sodium periodate is a better reagent than sodium bismuthate, manganese dioxide, or lead tetraacetate for the cleavage of unsaturated alpha-ketols and affords omega-oxo-alpha,beta-unsaturated acids in good yield. The combination of this cleavage reaction and a rhodium(I)-mediated decarbonylation of omega-oxo-alpha,beta-unsaturated esters derived from polycyclic systems provided an enantioselective synthesis of cyclic systems bearing contiguous quaternary centers where one of the centers possessed gem-dimethyl groups.
