The present invention provides a series of cytotoxic phosphoramidate analogs of 5-fluoro-2'-deoxyuridine of the general formula (I): ##STR1## wherein R.sup.1 is H, F or (C.sub.1 -C.sub.4)alkyl; R.sup.2 is CH.sub.2 CH.sub.2 X wherein X is Cl, Br, I or p-toluenesulfonyl; R.sup.3 is (C.sub.1 -C.sub.4)alkyl or CH.sub.2 CH.sub.2 X wherein X is Cl, Br, I or p-toluenesulfonyl; or wherein R.sup.2 and R.sup.3, taken together with the N atom, can be a 5- or 6-membered heterocyclic ring which is aliphatic or aliphatic interrupted by a ring oxygen or a second ring nitrogen; R.sup.4 is H, one equivalent of a pharmaceutically-acceptable cation or (4,4,6-trimethyltetrahydro-1,3-oxazin-2-yl)ethyl, and the pharmaceutically-acceptable salts thereof.
本发明提供了一系列细胞毒性的5-氟-2'-脱氧尿嘧啶的磷酰胺类似物,其一般式为(I):##STR1##其中R.sup.1为H,F或(C.sub.1 -C.sub.4)烷基;R.sup.2为CH.sub.2 CH.sub.2 X,其中X为Cl,Br,I或对甲苯磺酰基;R.sup.3为(C.sub.1 -C.sub.4)烷基或CH.sub.2 CH.sub.2 X,其中X为Cl,Br,I或对甲苯磺酰基;或其中R.sup.2和R.sup.3,与N原子一起,可以是一个5-或6-成员杂环,其为脂肪族的或被一个环氧原子或第二个环氮原子中断的脂肪族;R.sup.4为H,一个等效的药用阳离子或(4,4,6-三甲基四氢-1,3-噁唑啉-2-基)乙基,以及其药用盐。
