Reaktionsschritte

Di-tert-butylphenyliodonium chloride (443 mg; 1 mmol), ethyl orthopropionate (211 mg; 1.5 mmol), and trifluoromethanesulfonic acid (165 mg; 1.1 mmol) were dissolved in anhydrous methylene chloride (10 ml), and the resultant mixture was stirred for 2 hours at room temperature. The reaction mixture was alkalinized by adding 1% aqueous ammonia (10 ml), and extracted with methylene chloride twice, followed by drying. The solvent was evaporated, and the thus-obtained solid matter was washed with ether, to thereby yield 491 mg of the target compound as white crystals (yield: 91%).
