Ionic liquids were used to enhance as well as recycle the MacMillan's catalyst1for the Diels-Alder reaction. Using our developed protocol, Diels-Alder adducts were obtained in good yields and selectivities along the 6 times recycling of MacMillan's imidazolidinone catalyst1. Synthesis of steroid4is the major outcome of our developed protocol.

Ionic liquids with Lewis superacidic borenium cations were used as catalysts in solvent-less Diels–Alder cycloaddition. The extremely high catalytic activity correlated with the Lewis acidity, expressed as the Gutmann acceptor number.

AbstractIonic liquids (IL) are gaining importance as green solvents. Imidazolium ionic liquid [bmim]+[Cl]−, an environmentally benign solvent, was found to promote the Diels-Alder reaction between anthrone and maleimides at room temperature with excellent yields. The ionic liquid played a dual role as solvent and catalyst.

We studied how mixing ionic liquids affected the rate of the Diels Alder reaction between 9-anthracenemethanol and N-ethylmaleimide.
