  Total Syntheses of (±)-Isosteviol and (±)-Beyer-15-ene-3β,19-diol by Manganese(III)-Based Oxidative Quadruple Free-Radical Cyclization

  摘要：

  Tetraene 1 was prepared in nine steps from the known propargylic alcohol 7 in 17% overall yield or as a 2:1 E/Z mixture in only five steps in 7% overall yield. Oxidative cyclization of 1 with 2 equiv of Mn(OAc)(3). 2H(2)O and 1 equiv of Cu(OAc)(2) in MeOH at 25 degrees C provided 35% of tetracycle 2. Further elaboration provided (+/-)-isosteviol (3) in six steps in 51% yield and (+/-)-beyer-15-ene-3 beta,19-diol in four steps in 17% yield.
