실험 절차

Zinc dust (22.0 g, 0.33 mol, 37 eq) was added, in portions over 20 mins, to a solution of the propenyl intermediate 6 (5.5 g, 9.1 mmol, 1.0 eq) in 5% v/v formic acid/ethanol (55 mL), using an ice bath to maintain the temperature between 25-30° C. After 30 mins, the reaction mixture was filtered through a short bed of Celite®. The Celite® was washed with ethyl acetate (65 mL) and the combined organics were washed successively with water (35 mL), saturated sodium bicarbonate (35 mL) and brine (10 mL). The organic phase was dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, 90/10 v/v n-hexane/EtOAc) to afford the product as a pale yellow oil (3.6 g, 69.0%).
