development of a highly efficient catalytic asymmetric conjugate addition to α,β-unsaturated sulfones. Utilizing practical bifunctional organic catalysts and involving air- and moisture-tolerant conditions, conjugate additions of a wide range of Michael donors to α,β-unsaturated sulfones proceeded in excellent enantioselectivity/diastereoselectivity and high yield. This efficient and operationally
我们描述了对 α,β-不饱和砜的高效催化不对称共轭加成的发展。利用实用的双功能有机催化剂并涉及耐空气和耐湿条件,广泛的迈克尔供体与 α,β-不饱和砜的共轭加成以优异的对映选择性/非对映选择性和高产率进行。这种高效且操作简单的新型催化不对称反应应该为带有全碳四元立体中心的手性砜的不对称合成提供一种通用的方法。
