The method may further comprise purifying the oligonucleotide. Also included is a process for the synthesis of the sulfurizing agent.
专利号:US-7019127-B2 优先权日:1997-08-13 标 题 :Solution phase synthesis of oligonucleotides 发明人:REESE COLIN BERNARD; SONG QUANLAI 权利人:AVECIA LTD 摘要:A process for the synthesis in solution phase of a phosphorothioate triester is provided. The process comprises the solution phase coupling of an H-phosphonate with an alcohol in the presence of a coupling agent to form an H-phosphonate diester. The H-phosphonate diester is oxidised in situ with a sulfur transfer agent to produce the phosphorothioate triester. Preferably, the H-phosphonate and alcohol are protected nucleosides or oligonucleotides. Oligonucleotide H-phosphonates which can be used in the formation of phosphorothioate triesters are also provided.
