  描述：

  3α-hydroxy-5β-methoxy-4aβ-methylind-1(7α)-en-2-one 在 sodium periodate 作用下， 以 乙醚 、 水 为溶剂， 反应 18.0h， 生成 (1S,2S,3Z)-3-(carbomethoxymethylene)-2-(formylmethyl)-2-methyl-1-cyclopentyl methyl ether

  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.
