摘要

Scheme I" antiallergic and hypotensive activity of 2-alkynyladenosines has been reported by us and it was found that the presence of the triple bond is essential for the activities." 4'- Ethynylthymidine inhibits herpes simplex type 1 induced thymidine kinase.'* Thus, an alkynyl functional group attached to certain nucleosides would have interesting characteristics. In this paper, we describe the syntheses of 5-alkynyl-lP-~-ribofuranosylimidazole-4- ...
