highly enantioenriched cyclic β-aryl-substituted carbonyl compounds has been achieved through the RhI-catalyzed asymmetric 1,4-addition of an array of arylboronic acids to cyclic α,β-unsaturated carbonyl compounds. In the presence of 0.1 or 0.5 mol-% of the RhI/1g complex, the products of conjugate addition were isolated in 89 to 98 % ee and in good to excellent yield.
通过RhI催化的芳基
硼酸阵列与环状α,β-不饱和羰基化合物的不对称1,4-加成,实现了高度对映体富集的环状β-芳基取代羰基化合物的有效制备。在 0.1 或 0.5 mol% 的 RhI/1g 复合物的存在下,共轭加成产物的分离率为 89% 至 98% ee,产率良好至极好。
