, p. 549 - 550 (1995)
The hitherto unknown title compounds were stereospecifically synthesized by glycosylation of pyrimidine and purine aglycons with a suitably peracylated 3'-deoxy-β-L-erythro-pentofuranose, followed by removal of the protecting groups. All the prepared comp
Enantioselective total syntheses of slagenins A-C and their antipodes

Full details of the total syntheses of slagenins A-C (1a-c) and their antipodes (2a-c), novel bromopyrrole alkaloids with a unique tetrahydrofuro[2,3-d]imidazolidin-2-one moiety, are described in which their absolute stereochemistry was established. The key step in the syntheses involves the efficient condensation of dihydrofuran-3-one or glyoxal with urea to construct the slagenin bicycle core.
Monocyclic L-nucleosides with type 1 cytokine-inducing activity
Ramasamy, Kanda S.,Tam, Robert C.,Bard, Josie,Averett, Devron R.

A series of 1,2,4-triazole L-nucleosides were synthesized and evaluated for their ability to stimulate type i cytokine production by activated human T cells in direct comparison to the known active agent ribavirin. Among the compounds prepared, 1-β-L-ribofuranosyl-1,2,4-triazole-3-carboxamide (5, ICN 17261) was found to be the most uniformly potent compound. Conversion of the 3-carboxamide group of 5 to a carboxamidine functionality resulted in 1-β-L- ribofuranosyl-1,2,4-triazole-3-carboxamidine hydrochloride (10), which induced cytokine levels comparable to 5 for two of the three type 1 cytokines examined. Modification of the carbohydrate moiety of 5 provided compounds of reduced activity. Significantly, ICN 17261 offers interesting immunomodulatory potential for the treatment of diseases where type I cytokines play an important role.
