temperature, in a variety of solvents, and tolerate many functional groups. Alkylzirconium reagents undergo highly enantioselective copper-catalysed 1,4-addition reaction to cyclic enones. These reactions use alkylmetal species generated in situ from alkenes and the Schwartz reagent, and do not require premade organometallic reagents. The reactions have been performed on practical synthetic scales (2.5 mmol)
摘要 烷基锆试剂经历高度对映选择性的铜催化的1,4-加成反应成环烯酮。这些反应使用从烯烃和Schwartz试剂就地生成的烷基金属,不需要预制的有机金属试剂。该反应已在实用的合成规模(2.5 mmol)上进行,规模扩大到了10 mmol。反应在室温下在多种溶剂中进行,并能耐受许多官能团。 烷基锆试剂经历高度对映选择性的铜催化的1,4-加成反应成环烯酮。这些反应使用从烯烃和Schwartz试剂就地生成的烷基金属,不需要预制的有机金属试剂。该反应已在实用的合成规模(2.5 mmol)上进行,规模扩大到了10 mmol。反应在室温下在多种溶剂中进行,并能耐受许多官能团。
