技术领域
本发明属于有机合成技术领域,具体涉及一种N,N-二取代氨基-丙二腈类化合物的的合成方法。
背景技术
N,N-二取代氨基-丙二腈类化合物是一类比较重要的合成中间体,通过氰基衍生化,可以得到许多化学合成中有用的化合物,比如α-氨基酸。也能形成亚胺中间体和碳负离子,成为合成含氮杂环的重要前体。目前针对该类化合物的合成多用亚胺盐,季胺盐,硫代亚胺盐为原料,氰化钾为氰源(Justus LiebigsAnnalen der Chemie,(4),666-9；1976；Ger.Offen.,10057055,23May 2002；Journal of Organic Chemistry,50(21),4006-14；1985；Journal of theChemical Society,Perkin Transactions 1:Organic and Bio-OrganicChemistry(1972-1999),(11),2708-10；1979),步骤繁琐,而且用了剧毒的氰化钾。我们希望用原料易得的N,N-二取代的甲酰胺、相对低毒性的三甲基氰硅烷、铜金属催化剂加热条件下一步制得N,N-二取代氨基-丙二腈。

其中,(1)R1、R2不在同一个环系上时,两取代基可以相同,如甲基,乙基,等烷基基团；
(2)R1、R2不在同一个环系上时,两取代基可以不同,如R1可为甲基、乙基、丙基等烷基基团；R2可为苯基、苄基等芳基基团；
(3)R1、R2在同一环系上时,R1、R2连同N原子可为二氢吲哚基、1,2,3,4-四氢异喹啉基、哌啶基、吗啡啉基、4-甲基哌啶基。
在上述方法反应中,所用的铜催化剂的选择可为三氟甲烷磺酸铜、三氟甲烷磺酸亚铜、溴化铜、溴化亚铜、氯化铜、氯化亚铜、碘化亚铜。优选三氟甲烷磺酸铜。
在上述方法反应中,所用的溶剂可为正庚烷、1.2-二氯乙烷、乙腈、正己烷、环己烷、正壬烷、甲苯、四氢呋喃、1、4-二氧六环的一种或几种。优选正庚烷。
在上述方法反应中,加热所用的温度为20-120℃。
在上述方法反应中,反应中各物质的物质的量比为：N,N-二取代的甲酰胺：三甲基氰硅烷：铜催化剂：溶剂＝1：2-5：0.05-0.20：10-100。
