Specifically labelled methyl crepenynate and oleate have been synthesised from the C9 phosphoranes, Me[CH2]4·CC·CH2·CHPPh3 and Me[CH2]7·CHPPh3, respectively, and the C9 aldehyde ester, OCH·[CH2]7·CO2Me; methyl linoleate has been obtained by partial hydrogenation of the crepenynate. Carbon-14 was introduced into the C18 esters via the [9-14C]- and [1,9-14C]-aldehyde esters, and tritium via a reaction
分别由C 9磷烷,Me [CH 2 ] 4 ·C C·CH 2 ·CH PPh 3和Me [CH 2 ] 7 ·CH PPh 3以及C 9醛合成了特定标记的甲基戊二酸酯和油酸酯。酯,OCH·[CH 2 ] 7 ·CO 2 Me;亚油酸甲酯是通过对甲酚丁酸酯的部分氢化而获得的。碳14被引入到C 18个酯经由所述[9- 14 C] -和[1,9- 14 C] -醛酯,和氚通过the烷与tri化甲醇的反应。描述了通往标记的C 9醛酯的几种途径。
