Intramolecular Ene Reactions vs Competitive Pericyclic Processes: The Effect of Solvents and Salts on the Reaction of 5-Bromo-2-(3-methyl-2-butenyloxy)benzylidenemalonic Acid Dimethyl Ester

Salt Effects on Diels−Alder Reaction Kinetics

“…The use of MPAC has also been explored in some hetero-Diels−Alder reactions with good success in terms of enhanced stereoselectvities and yields …”
