Synthesis of N-substituted 1-amino-2,3-dihydro-1H-imidazole-2-thione-N-nucleosides and S-glycosylated derivatives

Fusion of the N-substituted 1-amino-2,3-dihydro-1H-imidazole-2-thiones 1-4 with the peracylated ribose 5 in the presence of iodine afforded the N-nucleosides 6-9 in moderate yields. Deblocking with NaOMe/MeOH gave the free nucleosides 10-13. Alternatively, silylation of 4 followed by ribosylation with 5 in the presence of TMSOTf as catalyst afforded 9 in moderate yield. Ribosylation of 4 with the chlorodeoxyribose derivative 15 as well as 5 in the presence of NaH in DMF afforded the thioglycosides 16 and 18, respectively. Deblocking of 16 and 18 with NaOMe/MeOH gave the free S-thioglycosides 17 and 19, respectively. Thermal rearrangement of 19 at high temperature in the presence of iodine furnished 13 in low yield. The new free nucleosides and thioglycosides were inactive against HIV-1 and HIV-2 induced cytopathicity in human MT-4 lymphocyte cells.
