important classes of compounds in terms of their usefulness in pharmaceuticals, materials, dyes and photo-catalysis. Here we present an unconventional FeCl3-alcohol catalysed one-pot method for their synthesis directly from aldehydes, 1,3-cyclohexanedione and amines. This method efficiently merged high atom-economy and diversity of multicomponent reaction with novel iron catalyzed dehydrogenation, using
