A stereocontrolled convergent synthesis of a DEFG-ring model compound of gambieric acids, highly potent antifungal marine polycyclic ether natural products, has been achieved based on Suzuki—Miyaura coupling. Conformational analysis of the model compound revealed that the nine-membered F-ring exists exclusively as a single stable conformer, as opposed to that of ciguatoxins.
基于铃木-Miyaura偶联,已经完成了冈比亚酸DEFG环模型化合物(高效抗真菌海洋多环醚天然产物)的立体控制收敛性合成。对模型化合物的构象分析表明,与雪茄毒素相反,该九元F环仅作为一个稳定的构象体存在。
