Synthesis of nucleoside phosphoramidite for rna oligonucleotide synthesis: All Rights Reserved. Synthesis of nucleoside phosphoramidite for rna oligonucleotide synthesis. Zhang, Biliang; Cui, Zhiyong (Peop. Rep. China ). Faming Zhuanli Shenqing Gongkai Shuomingshu CN 1900103 A 24 Jan 2007,22pp. (Chinese). (People's Republic of China). CODEN: CNXXEV. APPLICATION: CN 2010-35849 18 Jul 2005. DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) The general formula of nucleoside phosphoramidite is shown in formula I. Nucleoside phosphoramidites I [R1 is N-protected adenine, guanine, cytosine, uracil or relative derivs.; R2 is 4,4'-dimethoxytrityl or other protective groups for hydroxyl; R3 is aminophosphate ester or other phosphate groups; R4 is H, Me or other groups; R5 is 2,2-dimethyl-2-(o-nitrophenyl)acetyl or 2,2-dimethyl-2-(substituted o-nitrophenyl)acetyl] are prepd. 89992-70-1 which is the cas registry number of one of substances is just one of reagents here. The invention protects 2'-hydroxyl of nucleoside with [2,2-dimethyl-2-(o-nitro-phenyl)acetyl Me ether] (DNPA), which has compatibility with general protective groups for 5'-hydroxyl. DNPA group can be removed under mild conditions, thus the integrality of RNA is completely ensured. .
