実験手順

10 mL of methylene chloride was added to 1.097 g (4 mmol) of 4-(pyren-1-yl) butyl alcohol and stirred vigorously at room temperature for 10 min hour. The reaction was followed by addition of 1.292 g (1.5 Eq.) of PCC (Pyridinium chlorochromate) in 10 mL methylene chloride and the reaction mixture was stirred for 2 h. The reaction mixture was then diluted with 5 volumes of anhydrous ether (100 mL) and washed with 1:1 brine:water, saturated aq. Na2SO3 solution, and brine, respectively, dried over anhydrous Na2SO4 and concentrated to give the aldehyde. The crude product was purified by silica gel flash chromatography (hexanes: ethyl acetate, 9:1, rf: 0.4) to yield 1.06 g (97%). Most of the crude products were very clean and could be used directly for further applications.
