The MOB 2 generated in situ by the pyrolysis of itsdimer 3 participated in Diels-Alder reactions with various olefinic and acetylenic dienophiles at 220 °C to provide bicyclo[2.2.2]octenones and bicyclo[2.2.2]]octadienones, respectively. Reactions proceeded with high degree of regio- and stereoselectivity.
