Application

Three-Component coupling of benzyne, DMF, and active methylene compounds to produce coumarins

Typical procedure (Entry 1): A Schlenk tube is charged with KF (46.5 mg). The tube is evacuated at room temperature for 1 h before addition of DMF (4 mL), diethyl malonate (32 mg), and 2-(trimethylsilyl)phenyl trifluoromethanesulfonate (119.3 mg) under an argon atmosphere. The resulting mixture is stirred at 80 ºC for 5 h. The mixture is diluted with ethyl acetate and the organic solution is washed three times with brine. The organic layer is dried over MgSO₄ and the solvent is removed in vacuo. The residue is purified by silica-gel column chromatography to give ethyl 2-oxo-2H-chromene-3-carboxylate as a pale yellow solid (34.2 mg, 79 % yield based on diethyl malonate).
