ring-opening accompanies adduction to give 11 and two stereoisomers of gross structure 12. Dienes 1, 9 (X = OMe) and 9 (X = H) react at similar rates with N-methylmaleimide, discounting the alleged intramolecular retardation due to through space interaction between the hydroxy group and the diene system.
