Abstract

Abstract: The [BMIm][Pro] and Pro/MWCNTs (proline which supported on multi walled carbon nanotube) was synthesized and their activities in synthesis of various derivatives of 2‐amino‐4 H ‐pyrans in green media and room temperature conditions was investigated and compared. All the reactions resulted in moderate to excellent yields; however, reactions using Pro/MWCNTs catalyst were completed in relatively shorter reaction times. A novel heterogeneous Pro/MWCNTs was developed using immobilization of proline on MWCNTs via direct grafting amination approach for the first time. The reusability of two catalytic systems was also investigated.

And its application in the 2‐amino‐4 H ‐pyrans synthesis was compared with proline ionic liquid
