Reaktionsschritte
General procedure B using (S)-p-tol-BINAP and 3-benzylcyclopentenone (0.11 g, 0.7 mmol) gave, after 24 h at 0° C. and flash chromatography (6:1 pentane:diethyl ether), the title compound as a clear liquid (0.97 g, 85% yield). Spectroscopic data were consistent with previously reported data for this compound.12 [α]D25° C.−96° (c 1.3, CHCl3). Chiral HPLC analysis (Chiracel OD column) indicated that the title compound was obtained in 96% ee.
