반응 단계

To a solution of epoxy indenol 6 (0.24 g, 1.42 mmol) in 40 mL of CH2 Cl2, were added 2.16 g of oven dried Celite and PDC (2.16 g, 4 eq) at rt. After stirring at rt for 18 hr, the mixture was passed through 2 cm of flash silica gel pad, washed with 5% MeOH in CH2Cl2 (50 mL). The filtrate was concentrated and chromatographed with 35% EtOAc in hexane to give 0.18 g (75%) of indene-1-one 7 as colorless oil. The compound was identical with the literature by NMR (A. R. Daniewski; J. Kiegoel, J. Org. Chem. 1988, 53, 5534-5535).
