摘要

合成了N，N，N‘，N’-四甲基-N，N'-双（磺）联苯-4,4'-甲磺酸二胺酯（[TMBSPD][OMs]2）作为可回收离子液体，并通过各种技术对其进行了表征。该离子液体作为多功能促进剂有效地用于三组分合成2-氨基-3-氰基- 4h -吡喃。制备的2-氨基-3-氰基- 4h -吡喃不仅产率高，而且不使用有毒溶剂和催化剂。[TMBSPD][OMs]2离子液体也被回收再利用了4次，其活性没有明显下降。此外，还合成了一些新的2-氨基-3-氰基- 4h -吡喃衍生物。

A Novel Basic and Acidic Ionic Liquid as a Highly Effectual and Dual-Functional Catalyst for the Green Synthesis of 2-Amino-3-cyano-4H-pyrans

N,N,N',N'-Tetramethyl-N,N'-bis(sulfo)biphenyl-4,4'-diaminium mesylate ([TMBSPD][OMs]₂) was synthesized as a recyclable ionic liquid and characterized by various techniques. This ionic liquid was efficiently applied as a multifunctional promoter for the three-component synthesis of 2-amino-3-cyano-4H-pyrans. The 2-amino-3-cyano-4H-pyrans were prepared not only in high to excellent yields but also no toxic solvent or catalyst was used. [TMBSPD][OMs]₂ ionic liquid was also recovered and reused four times without the considerable decreasing in its activity. Also, some new derivatives of the 2-amino-3-cyano-4H-pyrans were synthesized by this method.
