    • Typically, a chloroform solution (10 mL) containing Acr+-Mes (12 mg, 2.9 × 10-5 mol) and DMA (60 mg, 2.9 × 10 -4 mol) in a Schlenk flask with a rubber septum was degassed by freeze-pump-thaw cycle three times and flushed with argon gas. The solution was then irradiated with a 500 W xenon lamp (Ushio Optical ModelX SX-UID 500XAMQ) through a color filter glass (Asahi Techno Glass Y43) transmitting λ > 430 nm at 298 K. After 4 h photoirradiation, dimethyllepidopterene was isolated by silica gel column chromatography (hexane/toluene 1/1, v/v) as pale yellow solid (12% yield, Dimethyllepidopterene: Anal.
