derivatives by copper(I) catalysis with two identical isatins in the presence of KHCO3 as a base is described. Furthermore, more complicated tryptanthrin derivatives are obtained in two steps with two different isatins in one pot. This work features readily available starting materials, mild reaction conditions, simple operation, good functional group tolerance, high yields and selectivity. This transformation
描述了一种在KHCO 3作为碱存在下,用两种相同的靛红铜( I ) 催化制备色胺菊酯及其衍生物的温和方法。此外,更复杂的色胺酮衍生物通过两步获得,一锅使用两种不同的靛红。该工作具有原料易得、反应条件温和、操作简单、官能团耐受性好、收率高、选择性高等特点。这种转化不仅为获取色胺酮及其衍生物提供了一种新方法,而且丰富了靛红和铜催化的化学性质。
