  Reductive cyclization of quinone methides

  摘要：

  The first use of reduced quinone methides for the formation of carbon-carbon bonds in cyclization reactions is described. Treatment of quinone methides with SmI2 resulted in intramolecular reaction with internal activated multiple bonds to afford 5- and 6-membered carbocycles in good yields. The activated multiple bonds used are aldehydes and alpha,beta-unsaturated esters and nitriles.
