The One

Palladium-catalyzed copper-free Sonogashira coupling of 2-bromocarbonyls is presented. This method afforded the 2-alkynylaryl carbonyls, useful synthons for the accomplishment of many carbocyclic and heterocyclic motifs. Significantly, the strategy was extended to the one-pot synthesis of isobenzofurans via reduction followed by intramolecular 5-exo-dig cyclization.

Sequential Reactions

A highly efficient protocol has been developed for the synthesis of diversely substituted isoindolo[2,1-b]isoquinolin-7(5H)-ones through sequential Cu(ii)-catalyzed Sonogashira coupling, intramolecular hydroamidation followed by palladium-catalyzed ligand free Heck reaction.
