derivative (1). Also, treatment of compound 1 with 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide or 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose afforded nucleosides 9 and 12, respectively. Furthermore, deprotection of the latter blocked nucleosides was achieved in methanolic ammonia to afford the desired free S-nucleoside derivatives 10 and 13, respectively. Some prepared products were screened for
