Herein, we report (R)-3,3′-(3,5-(CF3)2-C6H3)2-BINOL-catalyzed enantioselective conjugate addition of organic boronic acids to β-silyl-α,β-unsaturated ketones, furnishing moderate to excellent yields of the corresponding β-silyl carbonyl compounds with stereogenic centers in excellent enantioselectivities (up to 98% ee). Moreover, the catalytic system features mild reaction conditions, high efficiency
在此,我们报道了 ( R )-3,3'-(3,5-(CF 3 ) 2 -C 6 H 3 ) 2 -BINOL 催化的有机硼酸对映选择性共轭加成到 β-甲硅烷基-α,β-不饱和酮,以优异的对映选择性(高达 98% ee)提供中等至优异的具有立体异构中心的相应 β-甲硅烷基羰基化合物的收率。此外,该催化体系具有反应条件温和、效率高、底物适用范围广、易于放大等特点。
