标 题:Non-enzymatic large scale synthesis of RNA
发明人：KANAVARIOTI ANASTASSIA; DEAMER DAVID W; MONNARD PIERRE-ALAIN M; BERNASCONI CLAUDE F
摘要:This invention pertains to the development of methods that accomplish efficient, non-enzymatic, nucleic acid-directed (e.g. RNA-directed) nucleic acid (e.g. RNA) synthesis. In certain embodiments the methods provide conditions that favor oligouridylate synthesis with excellent yield and, at least, up to 30% regioselectivity favoring the RNA linkage. The methods preferably involve contacting, in the presence of lead ions (Pb 2+ ) and/or tin ions (Sn 2+ ) and, optionally, magnesium ions (Mg 2+ ), a template nucleic acid with a nucleotide derivatized with an imidazolide.

标 题:Methods for selective N-9 glycosylation of purines
发明人：ROBINS MORRIS J; ZHONG MINGHONG
权利人:UNIV BRIGHAM YOUNG
摘要:A process for providing regiospecific and highly stereoselective synthesis of 9-β anomeric purine nucleoside analogs is described. The introduction of the sugar moiety on to 6-(azolyl)-substituted purine bases is performed so that highly stereoselective formation of the β anomers of only the 9 position regioisomers of the purine nucleoside analogs (either D or L enantiomers) is obtained. This regiospecific and stereoselective introduction of the sugar moiety allows the synthesis of nucleoside analogs, and in particular 2′-deoxy, 3′-deoxy, 2′-deoxy-2′-halo-arabino and 2′,3′-dideoxy-2′-halo-threo purine nucleoside analogs, in high yields without formation of the 7-positional regioisomers. Processes for providing novel 6-(azolyl)purines for the regiospecific and highly stereoselective synthesis of 9-β anomeric purine nucleoside analogs are described. The compounds are drugs or intermediates to drugs.
