A fast selenylative spirocyclization of indolyl ynones mediated by PIFA has been developed. This transformation was enabled by the reactive RSeOCOCF3 species generated in situ from diselenides with PIFA, involving an electrophilic dearomative cascade cyclization.
在 PIFA 的介导下,开发出了一种吲哚基炔酮的快速硒化螺环化反应。这种转化是由二硒化物与 PIFA 在原位生成的活性 RSeOCOCF3 物种促成的,其中涉及亲电脱芳式级联环化。
