Feng, Bin-Bin published the artcileA Convenient Synthesis of Spiro[isoxazole-pyrazoloquinoline] Derivatives under Catalyst-Free Conditions, Product Details of C9H7NO2, the publication is Synthesis (2016), 48(1), 65-72, database is CAplus.
The same three-component reaction of aromatic aldehyde, 1H-indazol-6-amine and 3-phenylisoxazol-5(4H)-one in refluxing ethanol under catalyst-free conditions gave two entirely different kinds of products depending on the substituents on the benzene ring. The reaction selectively gave 5H-spiro[isoxazole-4,8′-pyrazolo[3,4-f]quinolin]-5-ones with strong electron-withdrawing groups on the aromatic aldehyde, while it resulted in ring-opened pyrazoloquinoline derivatives with other substituents. The former structure was confirmed by x-ray diffraction anal.
Synthesis published new progress about 1076-59-1. 1076-59-1 belongs to isoxazole, auxiliary class Oxazoline,Benzene,Ester, name is 3-Phenylisoxazol-5(2H)-one, and the molecular formula is C9H7NO2, Product Details of C9H7NO2.
