Photochemical Reactions of Imidazole-1-Sulfonates (Imidazylates)
摘要:
Imidazylates 1-3 were irradiated in methanol in the presence and in the absence of the electron donor-triethylamine, In each case photochemical deprotection occurred in excellent yield to form the partially protected sugar from which the imidazylate was synthesized. Reactions in the presence of triethylamine required much shorter irradiation times.

The present invention provides 5′-substituted-2′-F nucleoside analogs and oligomeric compounds comprising these nucleoside analogs. In one preferred embodiment the nucleoside analogs have either (R) or (5)-chirality at the 5′-position. These nucleoside analogs are expected to be useful for enhancing properties of oligomeric compounds including nuclease resistance.

[FR] L'invention concerne des analogues nucléosidiques 5'-substitués-2'-F et des composés oligomères comprenant ces analogues nucléosidiques. Dans un mode de réalisation préféré, les analogues nucléosidiques ont une chiralité (R) ou (S) sur la position 5'. Ces analogues nucléosidiques sont utiles pour l'amélioration de propriétés de composés oligomères, y compris une résistance aux nucléases.
