Research Abstract |
Synthetic method for 4-thiofuranoid glycal having ethynyl or cyano group at the 4'-position has been developed. On the basis of electrophilic glycosidation between the glycals and nucleobase as a key step, the target 4'-ethynyl(or cyano)-2'-deoxy-4'-thionucleosides could be obtained. The antiviral evaluation revealed that 4'-ethynyl-2'-deoxy-4'-thioguanosine was found to be highly potent and less toxic NRTI. 4-Ethynyl-4-thioribose derived from 4-Thiofuranoid glycal derived served as gycosyl donor in Vorbruggen glycosidation to give the taget 4'-ehtynyl-4'-thiocytidine.
