A PdI2/I2-catalyzed thiolation-annulation route of alkynes with azides and disulfides for the synthesis of 4-sulfenylisoquinolines is described. This route allows numerous 2-alkynylbenzyl azides to react with disulfides or 1,2-diphenyldiselane leading to the corresponding 4-chalcogen-substituted isoquinolines in moderate to good yields.
描述了一种PdI2/I2催化的炔烃与叠氮化物和二硫化物进行硫化-环化反应的路线,以合成4-硫烷基异喹啉。该路线允许多种2-炔基苯甲基叠氮化物与二硫化物或1,2-二苯基二硅烷反应,生成相应的4-硫族取代异喹啉,产率为中等至良好。
