The total synthesis of dolabriferol C was achieved by retro-Claisen fragmentation of its putative contiguous precursor, thus establishing the former as a plausible isolation artifact. The carbon skeleton of the precursor was assembled using a novel strategy involving a highly stereoselective three-component bisaldol coupling that sets the absolute configuration of seven (or eight) stereocenters in
dolabriferol C 的全合成是通过其推定的连续前体的逆克莱森碎裂实现的,从而将前者确立为一个合理的分离工件。前体的碳骨架是使用一种新的策略组装的,该策略涉及高度立体选择性的三组分双醛醇偶联,该策略在一锅法中设置了七个(或八个)立体中心的绝对构型。
