YieldReaction ConditionsOperation in experiment
55% General procedure: A dry sealed tube was charged with a magnetic stirrer, substituted<strong>[19591-17-4]N-(2-iodophenyl)acetamide</strong> (100 mg for each example,0.38 mmol), malononitrile or 2-sulfonylacetonitriles(0.46 mmol, 1.2 equiv), CuI (0.038 mmol, 0.1 equiv), L-proline(0.076 mmol, 0.2 equiv), and K2CO3 (0.76 mmol, 2 equiv) in0.77 mL of DMSO. The tube was evacuated and backfilled withargon and the process was repeated three times. The mixturewas stirred at 80 C for 12 h under an argon atmosphere.After the starting material was consumed completely,2-iodobenzaldehyde (0.4 mmol, 1.05 equiv) with 0.77 mL ofDMSO was charged successively to the tube via syringe,and then the resulting mixture was stirred at 80 C foranother 12 h under an argon atmosphere. After thereaction was complete, the reaction mixture was cooledto room temperature and the reaction mixture was partitionedbetween ethyl acetate or dichloromethane and water. Theorganic layer was separated and the aqueous layer was extractedwith ethyl acetate or dichloromethane for three times. Thecombined organic solution was washed with water, brine, driedover anhydrous Na2SO4, and concentrated under reducedpressure to give the crude product. Purification by chromatographyon silica gel using petroleum ether/ethyl acetate ordichloromethane/ethyl acetate as eluent provided the desiredproduct.
