A total synthesis of transtaganolide E and F, proposed intermediates in the biosynthesis of the potent transtaganolides, including an Ireland-Claisen rearrangement and a high-pressure intramolecular Diels-Alder cycloaddition reaction of an unactivated 2-pyrone derivative, is reported. The implication of the results to the proposed transtaganolides biosynthesis is discussed.
据报道,Transtaganolide E 和 F 的全合成是有效的 transtaganolide 生物合成中的中间体,包括爱尔兰-克莱森重排和未活化的 2-吡喃酮衍生物的高压分子内 Diels-Alder 环加成反应。讨论了结果对拟议的 transtaganolides 生物合成的影响。
