An efficient and convenient method was developed for the formation of 2-substituted benzothiazoles via a copper-catalyzed condensation 2-aminobenzenethiols with nitriles. The is applicable to wide range nitriles containing different functional groups furnishing excellent yields corresponding products.
Abstract A highly efficient and mild palladium‐catalyzed, one‐pot, four‐step cascade annulation has been developed to afford functionalized β‐ γ‐lactones in moderate good yields with high regio‐ diastereoselectivities ionic liquids. The employment of liquids under reaction conditions makes this transformation green practical. Especially, provided a novel convenient methodology for the construction naturally occurring biologically active γ‐lactones.
