Synthesis of 2',3'-dideoxy-3'-C-hydroxymethyl nucleosides as potential inhibitors of HIV
摘要:
A novel synthesis of 2',3'-dideoxy-3'-C-hydroxymethyl nucleosides is described. (2S,3R)-3-[[(4-Bromobenzyl)oxy]methyl]oxirane-2-methanol (1) was regioselectively alkylated using allylmagnesium bromide. The allyl double bond was oxidatively cleaved, and the product was treated with acidic methanol to give the requisite methyl furanoside derivative 5, which was subsequently condensed with purine and pyrimidine bases. Deblocking and separation of the anomers by chromatography afforded the alpha- and beta-nucleoside analogues.
