An efficient synthetic strategy to generate differently polysubstituted naphthalenes and iodonaphthalenes through a gold-catalyzed cyclization reaction of 1-arylalka-2,3-dienyl acetates was described. Due to the substituent loading capability of both the aromatic ring and the allene moiety, different substituents may be introduced to the different locations of the naphthalenes. A possible mechanism
描述了一种有效的合成策略,通过 1-arylalk-2,3-二烯乙酸酯的金催化环化反应生成不同多取代的萘和碘代萘。由于芳环和丙二烯部分的取代基负载能力,不同的取代基可被引入到萘的不同位置。在机理研究的基础上提出了涉及形成烯基和萘基金物种的反应的可能机制。金物种的碘化提供了碘代萘,这是通过偶联反应引入分子复杂性和多样性的有用构建块。
