Abstract:
A convenient route is reported for the synthesis of certain series of 2-thiohydantoins carrying various heterocyclic substituents such as 5-bromothienylidene 3a,b, 5-(2-carboxyphenylthio)-2-thienylidene 4a,b and 4H-thieno[2,3-b][1]benzothiopyran-4-one 5a,b. Glycosylation of these thiohydantoins afforded the S-glycosyl derivatives 10a-d. The synthesized compounds were tested for their activity against HIV-1 virus and as antitumor agents.
