Abstract
Solvent decides: Versatile copper nanoparticles (Cu NPs) on activated carbon have been found to catalyze the multicomponent synthesis of indolizines in dichloromethane and the synthesis of heterocyclic chalcones in the absence of solvent, in both cases, from pyridine-2-carbaldehyde derivatives, secondary amines, and terminal alkynes (see scheme).
