Synthesis and Structural Characterization of Two Types of Chromene Derivatives Containing Pyrazolone or Indol-2-one: Reaction and Chemoselectivity of Carbonyl and Aldehyde Groups

: Under the catalytic conditions of tetrahydropyrrole, an addition-elimination reaction of chromone aldehyde with methylpyrazolone or 2-indolinone is carried out to obtain two kinds of chromene derivatives containing pyrazolone or indol-2-one. The structures are identified by 1 H NMR, 13 C NMR, HPLC, HRMS and melting point measurements.

期刊介绍： University Chemistry is an educational research academic journal supervised by the Ministry of Education and co-sponsored by Peking University and the Chinese Chemical Society. It was founded in 1986 and changed to a monthly publication in January 2016. Its purpose is to promote and deepen the reform of university chemistry education and serve to improve the level of chemistry teaching in my country. The main columns are: Today's Chemistry, Teaching Research and Reform, Knowledge Introduction, Chemical Experiments, Teacher-Student Chats, Future Chemists, etc. The journal has been included in many databases such as China Journal Network Full-text Database, Wanfang Database, Taiwan Huayi Database, Chinese Science and Technology Journal Database (Full-text Edition), and American Chemical Abstracts.
