专利号:US-7342003-B2 优先权日:2001-10-25 标 题 :Synthesis of 2-aralkyloxyadenosines, 2-alkoxyadenosines, and their analogs 发明人:MOORMAN ALLAN R; SCANNELL MICHAEL; BALASUBRAMANIAN THIAGARAJAN; OUTCALT RUSSELL; LEUNG EDWARD 权利人:KING PHARMACEUTICALS RES & DEV 摘要:Provided is a method for the synthesis of an aralkyloxyadenosine or an alkoxyadenosine. The method includes protecting the hydroxyl sugar groups with a protecting group to produce a protected halogenated adenosine. The protected halogenated adenosine is alkoxylated, and the hydroxyl sugar groups of the protected halogenated adenosine are deprotected to provide the aralkyloxyadenosine or alkoxyadenosine.
