반응 조건

온도-40 °C

반응 단계

To a −40° C. solution of (E)-ethyl 3-(4-tert-butylphenyl)acrylate (1.0 g, 4.3 mol) in ether (20 mL), freshly prepared diazomethane was added dropwise over 10 minutes. Pd(OAc)2 (30 mg, 0.133 mol) was then added. The reaction mixture was stirred for another 10 min at −40° C., and then filtered through a pad of Celite® and precipitate washed with ether. The filtrate was concentrated in vacuo and the crude material was then purified via silica gel column chromatography to afford ethyl 2-(4-tert-butylphenyl)cyclopropanecarboxylate (0.9 g, 84%) as an oil.
