Chen, Jinjin published the artcileTransition-metal-free selective pyrimidines and pyridines formation from aromatic ketones, aldehydes and ammonium salts, Category: benzothiophene, the main research area is aryl methylketone arylaldehyde ammonium acetate sodium periodate tandem multicomponent; triarylpyrimidine preparation; acetophenone benzaldehyde ammonium iodide three component cyclocondensaton; triphenylpyridine preparation.
An efficient synthesis of pyrimidines and pyridines was developed from readily available aromatic ketones, aldehydes and ammonium salts under transition-metal-free conditions. In this strategy, ammonium salts were used as nitrogen sources and only water was generated as a nontoxic byproduct. A catalytic amount of NaIO4 played an important role in the selectivity control, whereas substituted pyridines were dominantly formed in its absence.
