Asymmetric methallylation of ketones catalyzed by a highly active organocatalyst 3,3'-F2-BINOL

Abstract

(S)-3,3'-F2-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 (S)-3,3'-F2-BINOL could be easily recovered and reused.
