The synthesis of racemic 2'-(trimethylammonium)ethyl-3-hexadecyloxy-2-fluoro-2-(methoxymethyl)prop-1-yl-phosphate (6), a fluorinated analogue of an anticancer active ether lipid 5 was realized with 3% overall yield in a nine-step synthesis starting from 2-methylene-1,3-propanediol (7) using a bromofluorination as the key step. Both enantiomers of the precursor 8 of the ether lipid 6 were synthesized

磷酸酯(6)的合成,用3实现了抗癌活性醚脂质5的
氟化类似物。从
2-亚甲基-1,3-丙二醇(7)开始的九步合成中总产率为5%,主要步骤为
溴氟化。醚脂质6的前体8的两种对映异构体都是通过
脂肪酶催化的二

水解(83%ee)或通过
脂肪酶催化的二醇22的乙酰化(82%ee)来合成的。在甲基
