실험 절차

In a sealed tube purged with nitrogen, 1-iodo-3,5-dimethoxybenzene (36) (0.78 g, 3.0 mmol), (1S,2R,4aS,8aS)-1-(hydroxymethyl)-2,5,5,8a-tetramethyl-decahydronaphthalen-2-ol (3) (0.65 g, 2.68 mmol), Cs2CO3 (1.3 g, 4.0 mmol), 3,4,7,8-tetramethyl-[1,10]-phenylthroline (0.12 g, 0.50 mmol), CuI (0.05 g, 0.3 mmol), diglyme (2 mL) and toluene (10 mL) were added. The reaction mixture was stirred at 120° C. for 18 h. The reaction was cooled to room temperature, diluted with EtOAc (300 mL) and washed with water (100 mL). The organic layer was dried (Na2SO4) and concentrated. Purification by column chromatography on silica gel (Hexanes/EtOAc, 2:1) gave (1S,2R,4aS,8aS)-1-(3,5-dimethoxyphenoxymethyl)-2,5,5,8a-tetramethyl-decahydronaphthalen-2-ol (37) (0.71 g, 70%) as a colourless oil.
