Guoqing Zhang, Xuepeng Zhang and their team at the University of Science and Technology of China first intended to construct a series of organic ligands for water-based acrylic paints. By performing a routine Claisen condensation reaction between a ketone and an ester, they obtained a number of pyridine-substituted β-diketone compounds as fluffy crystals, with varying positions of nitrogen-substitution in the pyridine ring.
