The first total synthesis of greensporone C, a cytotoxic 14-membered resorcylic acid lactone, has been accomplished via a longest linear sequence of 16 steps in 3.3% overall yield. The key features of the synthesis include Mitsunobu esterification and ring-closing metathesis to construct the macrocycle and establish the (E)-olefin geometry, respectively. Our synthesis also confirmed the absolute stereochemistry
Greensporone C(一种具有细胞毒性的14元间苯二酸内酯)的首次总合成已通过16个步骤的最长线性序列完成,总产率为3.3%。合成的关键特征包括Mitsunobu酯化和闭环易位,以分别构建大环并建立(E)-烯烃的几何形状。我们的合成也证实了天然产物的绝对立体化学。
