A synthetic route to the FGH ring system of gambierol, a marine polyether toxin isolated from the dinoflagellate Gambierdiscus toxicus, has been developed. The present synthesis features B-alkyl Suzuki coupling of the F and H rings, followed by ring-closure of the G ring and stereoselective installation of 1,3-diaxial methyl groups at C21 and C23.
已经开发了一种从甘氨酸的双鞭毛藻中分离出的海洋聚醚毒素甘比罗尔的FGH环系统的合成途径。本合成的特征在于F环和H环的B-烷基铃木偶联,随后是G环的闭环和在C21和C23处的1,3-二轴甲基的立体选择安装。
