Intramolecular and Intermolecular Lewis Acid Catalyzed Ene Reactions Using Ketones as Enophiles
Alkylaluminium halide catalyzed intramolecular ene reactions of β-keto esters proceed in high yield to give cyclohexanols, via either a type I or type II process.Treatment of β-keto ester 3 with Me2AlCl gives cis-fused ene adduct 5 in 67percent yield.Simi
