versatile method for the total synthesis of cyclic diphenyl ether-type diarylheptanoids, acerogenin C, acerogenin L, (±)-galeon, and (±)-pterocarine was described. The Ullmann reaction of suitably substituted linear diphenylheptanoids was employed for the intramolecular formation of the key ether intermediates as the final step. The prerequisite diarylheptanoids were prepared by a series of cross-aldol
描述了一种用于全合成环状二苯醚型二芳基庚烷、acerogenin C、acerogenin L、(±)-galeon 和 (±)-pterocarine 的通用方法。适当取代的线性二苯基庚烷类化合物的 Ullmann 反应用于关键醚中间体的分子内形成,作为最后一步。先决条件二芳基庚烷是通过一系列从容易获得的起始苯甲醛的交叉羟醛缩合反应制备的。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
