참여 물질

반응 단계

Into a 20 mL volume eggplant-shaped flask, 80 mg of the above-prepared 9,10-bis(t-butyldimethylsilyloxy)-2-iodo-9,10-dihydro-phenanthrene dimer, 10 mL of tetrahydrofuran, 43 mg of ethanol, and 0.4 mL of tetrabutylammonium fluoride were added and stirred at room temperature in air. The resultant reaction mixture was allowed to stand. Thereafter, the precipitate was collected by filtration and washed, thereby to give 28 mg of a phenanthrenequinone compound represented by the following chemical structural formula (1b-1) (hereinafter referred to as a “phenanthrenequinone compound (1b-1)”) (yield 76%) as a reddish brown-colored solid.
