A series of 5-substituted 2'-deoxy-4'-thiopyrimidine nucleosides was synthesized and evaluated as potential antiviral agents. A number of analogues such as 2'-deoxy-5-propyl-4'-thiouridine (3ii), 2'-deoxy-5-isopropyl-4'-thiouridine (3iii), 5-cyclopropyl-2'-deoxy-4'-thiouridine (3iv), 2'-deoxy-4'-thio-5-vinyluridine (3viii), and 5-(2-chloroethyl)-2'-deoxy-4'-thiouridin (3xx) were found to be highly active against herpes simplex virus type-1 (HSV-1) and varicella tester virus (VZV) in vitro with no significant cytotoxicity. The compound with the broadest spectrum of activity was 2'-deoxy-5-ethyl-4'-thiouridine (3i) which showed significant activity against HSV-1, HSV-2, and VZV.

5-(2,2-Difluorovinyl)uracil (IV) was synthesized from 2,4-dimethoxy-5-bromopyrimidine by sequential formylation, difluoromethylenation, and removal of the 2- and 4-methyl groups. Condensation of the trimethylsilyl derivative of IV with protected D-erythro-pentofuranosyl chloride followed by separation of anomers and deblocking gave 5-(2,2-difluorovinyl)-2'-deoxyuridine (V). Compound V was active against
