Reaction Steps

To a solution of 1′-(3-hydroxypropyl)-5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-2′(1′H)-one (2.00 g, 5.92 mmol) in dichloromethane (100 mL) was added Dess-Martin periodinane (3.70 g, 8.46 mmol). The reaction mixture was stirred at 0° C. for 17 h, diluted with ethyl acetate, washed with 10% sodium thiosulfate solution and saturated sodium bicarbonate solution and brine. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated in vacuo, the residue was subjected to column chromatography with ethyl acetate in hexanes (20% to 50% gradient) to afford 3-(2′-oxo-5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-1′(2′H)-yl)propanal (1.74 g, 87%): MS (ES+) m/z 336.1 (M+1).
