Zusammenfassung:The invention relates to (E)-5-(2-bromovinyl)-uridine and its derivatives of general formula VI, VI wherein R1 stands for a hydrogen atom, C1-8 alkanoyl group, benzoyl group or a benzoyl group substituted in para position either with a C1-4 alkyl group or a halogen atom, and a process for preparing them by brominating 2',3',5'-tri-O-acyl-5-ethyl-uridine of general formula IV, IV wherein R is identical with R1, except where R1 stands for a hydrogen atom, dehydrohalogenating the resulting dibromo compound of general formula V V and optionally deacylating it. The resulting compounds of general formula VI are exhibiting significant potency against Herpes simplex virus species and are of remarkably low acute toxicity.
