The strategy toward the synthesis of various 1,3-dienals or 1,3-dienones is disclosed between diazo compounds and furans, which features metal-free, additive-free, broad functional group tolerance, and readily accessible starting materials. Notably, this strategy is applicable in both intramolecular and intermolecular protocols. Mechanistic studies suggested that the reactions undergo a cyclopropa
在重氮化合物和呋喃之间公开了合成各种 1,3-二烯或 1,3-二烯的策略,其特点是无金属、无添加剂、广泛的官能团耐受性和易于获得的起始材料。值得注意的是,该策略适用于分子内和分子间协议。机理研究表明反应经历了环丙烷化/重排序列。用E / E -1,3-二烯,容易制备相应的N-甲苯磺酰腙,与苯硼酸作用形成双键迁移产物,吲哚通过[3+2]环化反应构建五元环。
