Abstract

The ene reaction of trisubstituted alkenes with electron-deficient nitriles proceeds smoothly in the presence of boron trichloride to afford β, γ-unsaturated ketones in high yields. Investigation of the stereochemistry of the ene products suggests that this ene reaction is a concerted one. Similar reactions of cyclic trisubstituted alkenes are also described.
