摘要
A series of heterocyclic compounds of triazole thione substituted by tetrazole ( I) were prepared using nicotinic acid as starting material through several steps. They reacted with 1-O-trifluoroacetyl-2,3,5-O-tri-benzoyl-beta-D-ribofuranose (II) in anhydrous CH2Cl2 at room temperature in the presence of BF3 . Et(2)O to give nine new nucleosides, named as 3-[5-(3-pyridyl)-tetrazol-2-yl-methylene]-4-aryl-1,2, 4-triazole-5-(4H)-thione-2,3,5-O-tribenzoyl-beta-D-ribo-furanoside (II) (Ar = C6H5, o-MeC(6)H(4), m-MeC(6)H(4), p-MeC(6)H(4), o-MeOC(6)H(4), p-MeOC(6)H(4), p-EtOC(6)H(3), 3, 4-Me(2)C(6)H(4), alpha-C10H7). The structures and compositions were characterized by means of elemental analysis and spectroscopic methods.
