5'-Azido and 5'-fluoro alpha-nucleosides as analogues of AZT and FLT.
5-Azido-2,5-dideoxy-beta-D-erythro-pentofuranosyl nucleosides 10 and their corresponding alpha-anomers 11 have been synthesized by condensation of methyl 3-O-acetyl-5-azido-2,5-dideoxy-beta-D-erythro-pentofuranoside (7) with silylated nucleobases followed by deprotection with methanolic ammonia. Reaction of silylated thymine (19) with methyl 2,3-di-O-benzoyl-5-deoxy-5-fluoro-D-arabino-pentofuranoside (15) and methyl 5-azido-2,3-di-O-benzoyl-5-deoxy-alpha-D-arabino-pentofuranoside (17 alpha) afforded a mixture of the alpha-nucleosides 20 and the acyclo nucleosides 5-fluoro- and 5-azido-2,3-O-dibenzoyl-5-deoxy-1-O-methyl-1-(thymin-1-yl)-D -arabinitol (22). Compounds 20 and 22 were deprotected with methanolic ammonia to give the acyclic nucleosides 21 and 23, respectively. The new nucleosides were inactive against HSV-1 and HIV-1.
