An acid-functionalized ionic liquids (ILs) catalyzed cascade decarboxylative cyclization of 2-arylanilines with α-oxocarboxylic acids was developed. This approach offered a sustainable and practical pathway to afford a library of quinoxalines...
A novel palladium-catalyzed Heck/[4+1] decarboxylative cyclization cascade of alkene-tethered aryl iodides with α-bromoacrylic acids is reported. This strategy employs α-bromoacrylic acids as a new C1 synthon to assemble diverse heteropolycycles,...
