Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 7689-03-4, Name is Campathecin, belongs to thiazines compound, is a common compound. In a pantent, author is Khodairy, A., once mentioned the new application about 7689-03-4, Name: Campathecin.
The Reaction of 1-Phenylpyrazolidine-3,5-dione with Active Nitriles Using Phase Transfer Catalysis Conditions Technique
Heterocyclization reaction of 1-phenylpyrazolidine-3,5-dione with some active nitriles and acrylonitriles is described. These cyclization reactions afforded novel heterocyclic derivatives such as pyrano[2,3-c]pyrazoles, pyrazolyl-thiazole, pyrazolyl-1,3-thiazines, and pyrazolyl-1,3-oxathiino[6,5-c]pyrazoles. Heating 1-phenylpyrazolidine-3,5-dione alone under phase transfer catalysis conditions afforded the tricyclic dipyrazolofurandione. The structure of the new products has been characterized by IR, NMR, mass spectra, and their elemental analyses.
