Research speed reading in 2021. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. , Recommanded Product: Campathecin, 7689-03-4, Name is Campathecin, molecular formula is C20H16N2O4, belongs to thiazines compound. In a document, author is Khodairy, A., introduce the new discover.
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.
