Abstract
An efficient synthesis of new 2-aminothiazole-annulated compounds is described via copper(II) triflate promoted sequential condensation, arylation, and heterocyclization reactions in one step. The reaction is compatible with a variety of substrates providing efficient access to many biologically important skeletons in good yields.
Key words
copper triflate - multicomponent reaction - naphthothiazole - domino synthesis - carbon disulfide
