for the preparation of 3′-O-lysophosphatidyl derivatives of 5′-deoxy-5-fluorouridine and 5′-deoxy-5′-(methylthio)adenosine, with the 2′-O-isomer of the latter compound also being prepared. The enhanced ability of lysophosphatidyl compounds to interact with lipid monolayers was also tested in comparison with that of the relevant free nucleosides.

DNA 的四个 3'-核苷酸的单[(2R)-2,3-二氢丙基]酯,由受保护的核苷亚磷酰胺和 [(4S)-2,2-二甲基-1,3-二氧戊环-4-基] 制备甲醇,在甘油部分的 C-1 羟基处通过脂肪酶催化的转酰基作用与有机溶剂中的活化棕榈酸酯进行区域选择性酰化,得到相关的 3'-O-溶血磷脂酰-2'-脱氧核苷。该合成还适用于制备 5'-脱氧-5-氟尿苷和 5'-脱氧-5'-(甲硫基)腺苷的 3'-O-溶血磷脂酰衍生物,后者的 2'-O-异构体化合物也在制备中。与相关游离核苷的能力相比,还测试了溶血磷脂酰化合物与脂质单层相互作用的增强能力。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
