A ruthenium-catalyzed enyne metathesis reaction followed by a cobalt-catalyzed Diels–Alder reaction and oxidation of the dihydroaromatic intermediate generates the two regioisomeric aromatic products in good overall yields in a one-pot procedure. The regiochemistry of the cycloaddition can be controlled by the ligand choice on the cobalt catalyst to generate the product with the 1,3,5- or the 1,2,4-substitution
钌催化的烯炔复分解反应,然后进行钴催化的狄尔斯-阿尔德反应,以及二氢芳族中间体的氧化反应,可以一锅法以良好的总收率产生两种区域异构的芳族产物。可以通过在钴催化剂上选择配体来控制环加成的区域化学,以主要产生具有1,3,5-或1,2,4-取代模式的产物。高官能团的耐受性用于生成双官能团结构单元,最后描述了前所未有的区域选择性Scholl反应。
