three-component coupling reaction of aldehydes, 1,3-dienes, and alkenylzirconium reagents was realized. The ligand- and additive-free protocol afforded a convenient approach to the synthesis of skipped diene compounds bearing various functionals (e.g., hydroxyl, carbonyl, halide) and heterocyclic groups. The products were readily transformed into structurally diverse polyenes. The utility of this reaction was
实现了区域和立体选择性镍催化的醛,1,3-二烯和烯基锆试剂的三组分偶联反应。不含配体和不含添加剂的方案为合成带有各种官能团(例如羟基,羰基,卤化物)和杂环基团的跳过的二烯化合物提供了一种简便的方法。产物容易转变成结构上不同的多烯。一锅操作和按比例放大制备也证明了该反应的实用性。
