应用
Aza-Morita-Baylis-Hillman Reaction with Ion-Supported Ph3P
Typical procedure (Entry 3, R = 4-Fluorophenyl): Methyl vinyl ketone (105 mg) is added to a solution of N-(4’-fluorobenzylidene)-4-methylbenzenesulfonamide (277 mg), 1-methyl-1-[4-(diphenylphosphino)benzyl]pyrrolidinium bromide (220 mg) and MS4Å (100 mg) in CH2Cl2 (4 mL). The mixture is stirred for 5 h at room temperature under an argon atmosphere. After the reaction, diethyl ether (10 mL) is added and the mixture is stirred for 30 min at 0 °C. The mixture is filtered and washed with diethyl ether. Removal of the solvent from the filtrates gives the corresponding product with 95 % purity. The product is purified by short flash column chromatography on silica gel (eluent: AcOEt/hexane=1/2) to give the desired pure product (347 mg, 100 %).
