Procedure
To a suspension of 8-chloro-9,10-dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquino[3,2-a]isoquinolin-7-ylium; chloride (0.2 g, 0.5 mmol) in anhydrous diethyl ether (5 mL) at 0° C. was added a solution of allylmagnesium chloride in tetrahydrofuran (1.3 M, 2.16 mL, 4 mmol) dropwise. After stirring at 0° C. for 30 min, the reaction was quenched by adding saturated aqueous ammonium chloride solution (10 mL). The mixture was extracted with diethyl ether (2×50 mL), washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was re-crystallized from diethyl ether to afford 8,8-diallyl-9,10-dimethoxy-5,8-dihydro-6H-[1,3]dioxolo[4,5-g]isoquino[3,2-a]isoquinoline (28 mg, 13%).
