The photoredox-assisted gold-catalyzed arylative cyclization of 1,6-enynes with aryldiazonium salts gives rise to cyclization products with the opposite configuration at the alkene than that obtained by gold(I)-catalyzed alkoxycyclization. The reaction occurs under mild conditions and shows high functional group tolerance.
光氧化还原辅助的金催化1,6-烯炔与芳基重氮盐的芳基化环化反应生成的环化产物在烯烃处的构型与通过金（I）催化的烷氧基环化反应得到的产物相反。该反应在温和条件下进行，并且显示出高官能团耐受性。
