资源简介：
The in situ generated o-alkynylthioureas obtain by reacting 2-(phenylethynyl)anilines and aryl isothiocynates undergo efficient cascade cyclization in the presence of Ag2CO3 to form indoloquinolines under microwave heating. The present tandem process allows the generation of a variety of indolo[2,3-b]quinolines derivatives in good to moderate yields with a wide functional group tolerance.
