Reaction Steps

Tert-butyl[(1R,5S,6S)-3-ethyl-6-(nitromethyl)bicyclo[3.2.0]hept-3-en-6-yl]acetate (7.0 g, 23.7 mmol) was dissolved in ethanol (60 mL) and water (21 mL). To the solution, iron powder (13.27 g, 237 mmol) and ammonium chloride (628.1 mg, 11.9 mmol) were added, and the mixture was stirred for 5.5 hours under heating to reflux. The mixture was allowed to cool, then diluted with saturated saline, a saturated aqueous solution of sodium bicarbonate, and ethyl acetate, and filtered through Celite to remove insoluble matter. The filtrate was separated into organic and aqueous layers. The organic layer was washed with saturated saline. The organic layer was dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure to obtain the compound of interest as a pale yellow oil substance (7.02 g, <100%).
