Compounds of formula (I):
in which Y is a halogen atom, preferably a bromine atom, each of R' and R2 is a hydrogen atom or an acyl radical of the formula
in which X is a C1-6 alkyl group or a carboxy group of the formula
in which Z is a branched- or straight-chain alkylene radical having from 1 to 4 carbon atoms in the chain, with the proviso that R' and R2 are not simultaneously hydrogen atoms or acetyl groups; are useful in the treatment of viral infection, particularly those caused by herpes viruses.
式(I)化合物:其中 Y 为卤素原子,最好是溴原子,R'和 R2 各为氢原子或式中的酰基,式中 X 为 C1-6 烷基或式中的羧基,式中 Z 为支链或直链亚烷基,链中有 1 至 4 个碳原子,但 R' 和 R2 不能同时为氢原子或乙酰基;可用于治疗病毒感染,特别是由疱疹病毒引起的感染。

Succinyl‐cycloSal‐phosphate triesters of ribo‐ and 2′‐deoxyribonucleosides were attached to aminomethyl polystyrene as an insoluble solid support and reacted with phosphate‐containing nucleophiles yielding nucleoside di‐ and triphosphates, nucleoside diphosphate sugars, and dinucleoside polyphosphates in high purity after cleavage from the solid support. Here, reactive cycloSal‐phosphate triesters were
