Functionalized benzimidazothiazoles were obtained in one step by a Pd-catalyzed multicomponent carbonylative heterocyclization process, starting from 2-prop-2-ynylsulfanyl-3 H-benzimidazolium salts, CO, a secondary amine, and O2. The PdI2/KI-catalyzed oxidative aminocarbonylation of the terminal triple bond was followed in situ by intramolecular conjugated addition and isomerization to give the final product in fair to good yields.
