- Abstract
Imidazolidin‐4‐one is used as a recoverable organocatalyst for the asymmetric Diels‐Alder reaction in the presence of catalytic amount of dicationic ionic liquid and trifluoroacetic acid as a co‐catalyst. The Diels‐Alder reaction between model substrate cyclopentadiene and crotonaldehyde gave the product in 95% conversion and 87% ee of the endo‐product. The catalyst was shown better reusability when the 20 mol% of dicationic ionic liquid was used and catalyst was reused upto 5 cycles, conversion remains upto 3 recycles but ee of endo‐9 was slightly droped.
