c-14-eicosatrienoic acid. They were obtained via coupling of (a) c-7,c-10,c-13-nonadecatrien-2-one with ethoxycarbonylmethylenetriphenylphosphorane and c-7,c-10,c-13-nonadecatrien-2-yl methane sulfonate with diethyl malonate, (b) l-bromo-c-2,c-5,c-8-tetradecatriene with 5-hexynoic acid, (c) 1-bromo-2,5-undecadiyne with the appropriately substituted 8-nonynoic acids and (d) from the correspondingly substituted 1-bromo
酸的下列基团的合成中描述:(1)3-甲基- Ç -2,Ç -8,Ç -11,Ç -14-,和3-甲基吨-2,Ç -8,Ç - 11,c -14-二十碳四烯酸和3-甲基-c -8,c -11,c -14-二十碳三烯酸,(b)c -8,c -11,c -14-二十碳三烯酸5-炔酸, (c)c -2,3-亚甲基-,t -2,3-亚甲基-,3,3-二甲基-和4,4-二甲基-c -8,c -11,c-14-二十碳三烯酸,(d)18-甲基-,(S)-18-甲基和19-甲基-c -8,c -11,c -14-二十碳三烯酸。它们是通过(a)c -7,c -10,c -13-十九碳三烯-2-酮与乙氧基羰基亚甲基三苯基膦烷和c -7,c -10,c -13-九碳三烯-2-基甲烷磺酸与二乙基酯的偶联而获得的。丙二酸酯,(b)l-溴-c -2,c -5,c使用标准程序,用5-己酸的-8-十四碳三烯,(c)用适当取代的8-壬酸的1-溴-2
