Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1127-45-3, is researched, SMILESS is OC1=CC=CC2=CC=C[N+]([O-])=C12, Molecular C9H7NO2Journal, Latvijas PSR Zinatnu Akademijas Vestis, Kimijas Serija called 8-Hydroxyquinophthalone derivatives, Author is Kacens, J.; Cebure, A.; Neilands, O., the main research direction is hydroxyquinonaphthalone; quinophthalone hydroxy.Recommanded Product: 8-Hydroxyquinoline 1-oxide.
8-Acetoxyquinophthalone (I, R = Ac, X = H) (II) was prepared in 62% yield by reaction of 8-quinolinol oxide with 1,3-indandione in Ac2O. Analogously prepared was I (R = Ac, X = Cl) in 62% yield. Hydrolysis of the acetate gave the corresponding alcs. (I, R = H, (Cl). Treatment of II with SO2Cl2 gave indandione (III, X = H). Analogously III (X = C) was obtained.
Compound(1127-45-3)Recommanded Product: 8-Hydroxyquinoline 1-oxide received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(8-Hydroxyquinoline 1-oxide), if you are interested, you can check out my other related articles.
