A method for the synthesis of chiral cyclic analogues of platelet-activating factor (PAF) is reported. Treatment of suitably substituted derivatives of 2-deoxy-D-erythro-pentose with phosphorus oxychloride, followed by choline p-toluenesulfonate generates cyclic phospholipids in good yield. Further chemical modification produces other compounds including optically active gamma-butyrolactones such as
报道了一种合成血小板活化因子(PAF)的手性环状类似物的方法。用氯氧化磷处理2-脱氧-D-赤-戊糖的适当取代的衍生物,然后用胆碱对甲苯磺酸盐处理,可以高收率产生环状磷脂。进一步的化学修饰会产生其他化合物,包括旋光性的γ-丁内酯,例如2-脱氧-5-O-十六烷基-3-O-磷胆酰基-D-赤型戊酮-1、4-内酯和2-脱氧-3-O-十六烷基-5-O-磷胆酰基-D-赤-戊基-1,4-内酯。所有磷脂都是PAF诱导的人血小板聚集的弱拮抗剂,而两个类似物是弱激动剂。提出的化学方法对于合成其他构象受限的PAF类似物应该是有用的。
