Versuchsvorschrift

Diethylzinc addition to 1-(1-cyclohexenyl)-ethanone (1.04 mL, 8.05 mmol) was performed according to general procedure A using 2 mol % of Compound B enantiomer (88 mg). The product was purified by column chromatography (hexanes/EtOAc: 96/4) to give 697.1 mg of 9 (56% yield, 96% ee) of a colorless oil: [60 ]D 20=+5.9 (c 3.0, MeOH). [Published [α]D 20=+0.7 (c 3.0, MeOH, 51% ee)].
