Various 2-substituted all-cis-8,11,14-eicosatrienoic acids have been prepared via coupling of all-cis-6,9,12-octadecatrienyl methanesulfonate with diethyl malonate, substituted diethyl malonates, ethyl cyanoacetate or ethyl 2-cyanohexanoate. The substituents are: COOH, COOCH3, COOC4H9, COOC7H15, CH2OH, CH3, C4H9, C6H5, CH2OCH3, NHCOCH3, NH2.HCl, F, OCH3, CN and both CN and C4H9.
通过将全顺式-6,9,12-十八碳三烯基甲磺酸酯与丙二酸二乙酯,取代的丙二酸二乙酯,氰基乙酸乙酯或2-氰基己酸乙酯偶联,制备了各种2-取代的全顺式-8,11,14-二十碳三烯酸。取代基为:COOH,COOCH 3,COOC 4 H 9,COOC 7 H 15,CH 2 OH,CH 3,C 4 H 9,C 6 H 5,CH 2 OCH 3,NHCOCH 3,NH 2 .HCl,F ,OCH 3,CN以及CN和C4 H 9。
