We report a photoinduced phenanthrene synthesis from aryl iodides and styrenes through an arylation/cyclization cascade. Compared to prior methods, this approach obviates the need for hazardous reagents and provides access to unsymmetrical phenanthrenes with good functional group tolerance. Mechanistic studies revealed that photoexcitation of aryl iodides leads to homolytic C–I bond cleavage. Arylation
我们通过芳基化/环化级联报告了芳基碘化物和苯乙烯的光诱导菲合成。与以前的方法相比,这种方法避免了对危险试剂的需要,并提供了获得具有良好官能团耐受性的不对称菲的途径。机理研究表明,芳基碘化物的光激发会导致均裂的 C-I 键断裂。苯乙烯与形成的芳基自由基物种的芳基化提供二苯乙烯衍生物,其经历由原位产生的碘促进的光诱导环化以产生菲产物。
