    • 2 (0.03 mmol) with 3(G2[Me]) (0.03 mmol) at room temperature in dry dichloromethane (1.5 mL) for 2 h under an argon atmosphere. To the resulting bluish green solution of the catalyst was added a mixture of diene (1.5 mmol) and dienophile (0.3 mmol) in dry dichloromethane (1.5 mL) at 0 °C under an argon atmosphere. The resulting mixture was stirred for 2-16 h at room temperature (monitored by TLC). It was then quenched with water and was subjected to the usual extractive workup with dichloromethane. The residual oil obtained after evaporation of dichloromethane, which was dried over magnesium sulfate, was purified by column chromatography on silica gel to give the corresponding Diels-Alder adducts.
