Asymmetric Methallylation of Ketones Catalyzed by a Highly Active Organocatalyst 3,3′‑F<sub>2</sub>‑BINOL
2013-04-05T00:00:00Z (GMT) by
(<i>S</i>)-3,3′-F<sub>2</sub>-BINOL has been synthesized for the first time and demonstrated as a highly active organocatalyst for asymmetric methallylation of ketones. Up to 98:2 enantioselectivity and 99% yield were obtained with 5 mol % catalyst loading. The catalyst (<i>S</i>)-3,3′-F<sub>2</sub>-BINOL could be easily recovered and reused.
