  Synthesis of Acyclic C‐Nucleoside Analogues Using (E)‐1,2‐Dideoxy‐1‐dimethylamino‐4,5:6,7‐di‐O‐isopropylidene‐d‐arabino‐hept‐1‐en‐3‐ulose

  摘要：

  1-Deoxy-3,4:5,6-di-O-isopropylidene-D-arabino-hex-2-ulose reacted with N,N-dimethylformamide dimethyl acetal and tert-butoxy [bis(dimethylamino)] methane, respectively, to furnish (E)-1,2-dideoxy-1-dimethylamino-4,5:6,7-di-O-isopropylidene-D-arabino-hept-1-en-3-ulose. This push-pull activated heptenulose underwent ring closure reactions with various N,N'-nucleophiles like hydrazine hydrate, amidinium, guanidinium and isothiouronium salts in the presence of bases to yield pyrazole and pyrimidine derivatives, respectively, all of which derivatized with a di-O-isopropylidenated tetritol side chain. The isopropylidene groups were removed with methanolic HCl in the pyrazole series, whereas aq TFA was used in the case of pyrimidine analogues.
