18,18,18-heptadecafluoro-octadec-8-enoic acid is reported, starting from 1,8-octanediol and 1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-heptadecafluoro-10-iododecane. The key step is a Wittig reaction to form the C8–C9 double bond with a Z:E isomeric ratio of 10:1. The route should be generally applicable to the synthesis of highly fluorinated monounsaturated fatty acids.
五步合成Z -11,11,12,12,13,13,14,14,15,15,16,16,17,17,18,18,18-十七氟十八烷-8-烯酸据报道,从1,8-辛二醇和1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-七十七氟-10-碘十二烷开始。关键步骤是维蒂希反应,形成Z:E异构体比率为10:1的C8-C9双键。该路线通常应适用于高度氟化的单不饱和脂肪酸的合成。
