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.

A highly efficient enantioselective nitroso Diels–Alder reaction of 6-methyl-2-nitroso pyridine with various 1,3-dienes was successfully developed using a copper(i)/(S)–TF-BiphamPhos complex as the catalyst. For most of the cyclic dienes, the cycloadducts were obtained in high yields with excellent regio-, and stereoselectivities. Acyclic 2-silyloxy-1,3-diene also worked well in the reaction.

We have demonstrated a Diels–Alder reaction of an o-quinone generated in an electrochemical flow microreactor. In the flow microreactor system, 4-tert-butyl-o-benzoquinone was easily electrogenerated from 4-tert-butylpyrocatechol in the absence of chemical oxidants and then rapidly used, without decomposing, in a subsequent Diels–Adler reaction with various fulvenes to give the desired products efficiently.
