cycloalkenones 1 undergo an iron(III)-catalyzed vinylogous Michael reaction − a sequence of enone−dienol tautomerism, [4+2]-cycloaddition, and retro-aldol reaction − with quinone derivatives 3. A variety of products is obtained ranging from meta-terphenyl precursors 5 to dihydronaphthobenzofurans 7. Reaction of 1,2-naphthoquinone (3e) with vinylogous donors 1 yields cross-coupled products 12, which
接受体取代环烯酮1经历的铁(III)催化插烯迈克尔反应-烯酮二烯醇互变异构的序列,[4 + 2] -环,和复古醛醇缩合反应-与醌衍生物3。获得了各种产品,范围从间三联苯前体5到二氢萘苯并呋喃7。1,2-萘醌(3e)与乙烯基供体1的反应产生交叉偶联产物12,该产物可以进一步转化为高度官能化的联芳基化合物13和14。
