Synthetic method of imidazopyridine compounds
-
Paragraph 0056; 0065-0068, (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.
Method for synthesizing 2-arylimidazo[1, 2-a]pyridine compound
-
Paragraph 0093; 0094; 0095; 0096, (2018/11/27)
The invention discloses a method for synthesizing a 2-arylimidazo[1, 2-a]pyridine compound and belongs to the technical field of organic synthesis. The method comprises that an ethylbenzene compound,dibromohydantoin DBH and t-butyl hydroperoxide TBHP are added into water and undergo a reaction at 60 DEG C, an inorganic base and an alpha-aminopyridine compound are added into the reaction product and the mixture undergoes a reaction at 80 DEG C to produce a desired product 2-arylimidazo[1, 2-a]pyridine compound. The 2-arylimidazo[1, 2-a]pyridine compound is synthesized from the ethylbenzene compound which is cheaper and more readily available than the 2-arylimidazo[1, 2-a]pyridine compounds such as 2-bromoacetophenone commonly used in the industry.
