The synthesis of optically active phosphatidylcholines (D- and L-4) containing two of the same fatty acid moieties in a molecule is described. Optically pure D-enantiomers (D-4) were obtained from 2, 3-di-O-acyl-sn-glycerol (D-1) in high yield by phosphorylation with phosphorus oxychloride and subsequent treatment with choline tosylate (11a). L-Enantiomers (L-4) were also prepared in a similar manner from 1, 2-di-O-acyl-sn-glycerol (L-1). The whole procedure is easy and useful for the synthesis of enantiomeric phosphatidylcholines.
本文报道了在分子中含两个相同脂肪酸部分的具有光学活性的磷脂酰胆碱(D-4 和 L-4)的合成方法。高收率地由2,3-二-O-酰基-sn-甘油(D-1)经氯氧磷磷酸化后再与甲苯磺酸胆碱(11a)反应得到了具有光学纯的D-对映体(D-4)。L-对映体(L-4)也是以相似的方式从1,2-二-O-酰基-sn-甘油(L-1)制备得到。整个过程简便且适用于手性磷脂酰胆碱的合成。
