专利号:US-5861532-A 优先权日:1997-03-04 标 题:Solid-phase synthesis of N-alkyl amides 发明人:BROWN EDWARD G; NUSS JOHN M 权利人:CHIRON CORP 摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.
