    • 2 was further introduced at the desired pressure. After the reaction for 2 h, the reactor was cooled to 0°C with ice quickly and the pressure was released slowly. The MgO was removed by filtration, and the products and yields were determined by GC-MS/MS (Varian CP3800/1200L) with decane as an internal reference. Isolated yields were obtained after purification using silica-gel chromatography

    • We have also examined the reaction of other cyclic ketones, such as 2-methyl-cyclopentan-1, 3-dione, and obtained polycyclic compounds with the yields of 71% under the same condition in the case of 2a
