3-(3-iodophenyl)-3-oxopropanenitrile

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of 2-(3-iodobenzoyl)acetonitrile (36.2 g, 133.5 mmol) and N,N-diphenylformamidine (26.2 g, 133.5 mmol) in toluene (200 ml) was heated at reflux under a nitrogen atmosphere. After 8 h, the reaction mixture was cooled to room temperature and diluted with ether (200 ml) to give 2-(3-iodobenzoyl)-3-phenylaminoacrylonitrile (31.2 g) as a solid. was heated at reflux under a nitrogen atmosphere

反応条件: temp:-50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: n-Butyllithium (30.5 ml, 76 mmol, 2.5 M solution in hexane) was added dropwise to a cooled (0° C.) solution of diisopropylamine (10.6 ml, 76 mmol) in 10 ml dry tetrahydrofuran. Once addition was complete, the solution was kept at 0° C. for 10 minutes and was then cooled to −50° C. This cold LDA solution was then added to a −50° C. solution of acetonitrile (2.37 ml, 45.3 mmol) and ethyl 4-iodobenzoate (10.0 g, 36.2 mmol) in dry tetrahydrofuran (18 ml). Once addition was complete, the reaction was stirred at −50° C. for 3 hours and was subsequently warmed to 0° C. Saturated ammonium chloride was added (20 ml) and the reaction mixture was allowed to warm to room temperature. The product was extracted into ether and washed with 1N hydrochloric acid (50 ml). The organics were washed with brine (50 ml), dried over MgSO4 and then concentrated in vacuo to a red oil. The oil was purified through a small plug of silica gel using 3:1-2:1 hexanes/ethyl acetate as eluent. Concentration of the column fractions in vacuo gave 2-(3-iodobenzoyl)-acetonitrile (8.3 g) as a yellow oil.
