Palladium-catalyzed cascade reactions is now establish as a captivating branch of organic chemistry,since they usually proceed under mild reaction conditions,tolerant of many functional groups and also fall under the umbrella of green chemistry.[1] Recently,we had investigated various palladium(II)-catalyzed cascade of alkynes with alkenes in ionic liquids(Scheme 1,Path a).[2] As our part of research program in nucleopalladation and Pd-catalyzedcross-coupling reactions in ionic liquids,we wish to present the first example of palladium-catalyzed intermolecular cascade annulation of alkynes with alkenes in ionic liquids(Scheme 1,Path b).
