Ene reaction
Chemical reaction
In organic chemistry, the ene reaction (also known as the Alder-ene reaction by its discoverer Kurt Alder in 1943) is a chemical reaction between a relatively electron-rich allyl group (the ene) and an electron-poor π bond (the enophile). The reaction is a pericyclic group transfer; the enophile attacks to the ene to form a new σ bond with an allylic rearrangement and concomitant hydrogen migration: The reaction resembles the Diels–Alder cyclization, with similar activating groups and transition geometries, but is much less spontaneous.

It usually requires highly activated substrates, high temperatures, or a catalytic Lewis acid. Nevertheless, it has excellent functional group tolerance.
