asymmetric conjugate addition reactions of alkylzirconium species to acyclic enones are reported. The alkylzirconium nucleophiles are generated in situ by hydrozirconation of alkenes with the Schwartz reagent. The reaction proceeds under mild and convenient conditions. A variety of functionalized nucleophiles can be used, and the method tolerates some variation in enone scope. The method uses a new chiral
据报道烷基锆物种到无环烯酮的催化不对称共轭加成反应。烷基锆亲核试剂是通过用Schwartz试剂将烯烃加氢锆原位生成的。反应在温和方便的条件下进行。可以使用多种功能化的亲核试剂,该方法可以耐受烯酮范围的某些变化。该方法在三氟甲磺酸铜络合物中使用了一种新的手性非外消旋亚磷酰胺配体。
