Participants

Reaction Steps

To a suspension of (+)-(4aR)-(10bR)-4-methyl-8-(3-formylphenyl)-10b-methyl-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]quinolin-3-one (30 mg, 0.09 mmol), in 0.75 mL of methanol was added benzhydryl amine (0.09 mmol), sodium cyanoborohydride (0.09 mmol) and 2 drops of glacial acetic acid (mixture became homogeneous; pH =4). The reaction was stirred at room temperature for 60 h. The mixture was diluted with ethyl acetate, saturated aqueous sodium bicarbonate solution was added, and the resulting mixture was extracted repeatedly with ethyl acetate. The combined organic extracts were dried over sodium sulfate, concentrated, and purified by silica gel chromatography (ethyl acetate eluent), followed by trituration of the resulting oil with ether/hexanes, to give 36 mg (80%) of the title compound as a white solid. mp 55°-57°. FDMS: m/e=500. α[D]589 =+48.40 (c=0.64, methanol).
