A catalytic enantioselective addition reaction of alkylzirconium species to aromatic aldehydes is reported. The reaction, facilitated by a chiral nonracemic diol ligand complex with Ti(OiPr)4, proceeds under mild and convenient conditions, and no premade organometallic reagents are required since the alkylzirconium nucleophiles are generated in situ by hydrozirconation of alkenes with the Schwartz
报道了烷基锆物种与芳香醛的催化对映选择性加成反应。该反应由手性非外消旋二醇配体与 Ti(OiPr)4 配合物促进,在温和方便的条件下进行,并且不需要预制的有机金属试剂,因为烷基锆亲核试剂是通过烯烃与 Schwartz 试剂的氢化锆化原位生成的。该方法与功能化亲核试剂和广泛的芳香醛兼容。
