Ionic-Liquid-Mediated MacMillan’s Catalyst for Diels-Alder Reaction

الملخص EN

Ionic liquids were used to enhance as well as recycle the MacMillan's catalyst 1 for 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 catalyst 1.

Synthesis of steroid 4 is the major outcome of our developed protocol.
