Bi(OTf) 3 -mediated intramolecular hydroamination of 2-aminostilbenes for the synthesis of 2-arylindolines
摘要:
An efficient Bi(OTf)(3)-mediated intramolecular hydroamination of 2-aminostilbenes for the synthesis of various 2-arylindolines has been developed. Various advantages using Bi(OTf)(3) as a catalyst, such as the operationally easy, simple, and safe procedure, good to excellent chemical yields, and the use of relatively low catalyst loading are noteworthy.
