| abstract |
The invention belongs to the technical field of organic synthesis, and specifically discloses a variety of pyrazoloquinoline derivatives having the chemical structure of formula (I), wherein the substituent R 1 represents a phenyl group, a substituted phenyl group, a naphthyl group or an alkyl group, Substituent R 2 represents phenyl or substituted phenyl, and substituent R 3 represents phenyl, substituted phenyl, alkyl or oxyalkylene. The present invention also provides a method for synthesizing such compounds. The target compound is obtained by one-step reaction of a 2-pyrazole aniline compound and a 1,3-dicarbonyl compound under a metal-free catalysis condition, and the reaction conditions are mild and the reaction yield is relatively low. high. |
