EDDF–ethylene glycol, an ambiphilic catalytic system has been employed for the mild and rapid synthesis of various 3-indolochromenes and 3-indoloxanthenesviaa one-pot MCR. Besides recyclability of the catalyst, the present method circumvents the formation of any by-products.
EDDF-乙二醇,一种两性催化系统已被用于温和快速合成各种3-吲哚色酮和3-吲哚氧蒽,通过一锅多组分反应。除了催化剂的可回收性外,该方法还避免了任何副产物的形成。
