cui nanoparticles as an expedient and recyclable catalyst for the synthesis of n-cyclohexyl-3-aryl-quinoxaline-2-amines in ethanol via a multi-component reaction are established. the products were separated from the catalyst simply by filtration. the catalyst could be recycled and reused for several times without noticeably decreasing the catalytic activity.

An efficient synthesis of isoquinoline-2,3-dicarboxylates is described via one-pot reactions of isoquinoline and alkyl bromids with dialkyl acetylenedicarboxylates in water at 70oC. The mild reaction conditions and high yields of the products exhibit the good synthetic advantage of these methods. 

While some sequential electrophilic aromatic substitution reactions, known as tandem/domino/cascade reactions, have been reported for the construction of aromatic single skeletons, one of the most interesting and challenging possibilities remains the one-pot build-up of a complex aromatic molecule from multiple starting components, i.e., ultimately multi-component electrophilic aromatic substit...
