selective N-arylation of amines or azoles with aryl halides, methyl-α-d-glucopyranoside (MG) was found to function as a green ligand of copper powder. In addition, nitrogenheterocyclic amine compounds can also undergo the N-arylation coupling with heterocyclic aryl chlorides. This process allows access to a variety of aromatic amines and aryl azoles under mild reaction conditions, has good tolerance, and

The vortex fluidic device (VFD) is effective in modulating the synthesis of pyrimidine and quinoxaline-based compounds at room temperature and in high yield. The formation of the C–N bond occurs in the absence of a transition-metal catalyst, which avoids the contamination of the products with trace amounts of a transition metal. The systematic investigation of the operating parameters for the microfluidic

clean, mild and sustainable method for the functionalization of pyridines and their analogues is reported. A zinc‐based Lewis acid is used to activate pyridine and its analogues towards nucleophilic aromatic substitution, conjugate addition, and cyclization reactions by binding to the nitrogen on the pyridine ring and activating the pyridine ring core towards further functionalization.
