    • 2 (12 mL) was then added and the mixture was stirred under ethylene at 20°C during 5 d. The volatiles were eliminated under reduced pressure and the residue was purified by flash chromatography (5% EtOAc in hexane) to give rac-cis-22 (100 mg, 25%) and rac-trans-22 (100 mg, 25%) in order effractions eluted.
