Paragraph 0054-0067, (2021/03/24)
The invention provides a novel method for synthesizing imidazopyridine compounds. According to the invention, aminopyridine compounds and sulfur ylide are used as original reaction substrates, iron phthalocyanine (FeIIPc) is used as a catalyst, and a series of the imidazopyridine compounds are obtained under the condition that the advantages of mildness, greenness, high efficiency, wide substrateuniversality and the like are achieved.

The C3-functionalized imidazo[1,2-a]pyridines are versatile nitrogen-fused heterocycles; however, the methods for the C3 acyloxylation of imidazo[1,2-a]pyridines have never been reported. Herein we demonstrate the electrochemical oxidative C3 acyloxylation of imidazo[1,2-a]pyridines for the first time. Notably, by using electricity, the electrochemical oxidative C3 acyloxylation of imidazo[1,2-a]pyridines was carried out under mild conditions. Moreover, in addition to aromatic carboxylic acids, alkyl carboxylic acids were also competent substrates.
