Electric Literature of 14348-75-5, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 14348-75-5, Name is 2,7-Dibromo-9H-fluoren-9-one, SMILES is C3=C2C1=C(C=C(Br)C=C1)C(C2=CC(=C3)Br)=O, belongs to phthalazines compound. In a article, author is Turhan, K., introduce new discover of the category.
Efficient One-Pot Synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11-trione Derivatives Catalyzed by Y(OTf)(3)
In this study, substituted 2H-indazolo[2,1-b]phthalazine-1,6,11-triones, that may possess biological activity, have been synthesized via one-pot three-component cyclocondensation reaction of aromatic aldehydes, cyclic 1,3-dione and phthalhydrazide in ethanol catalyzed by Y(OTf)(3) with good to excellent yields. The structures of all synthesized compounds, 3,4-dihydro-13-phenyl-2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione (4a), 13-(4-cyanophenyl)-3,4-dihydro-2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione (4b), 3,4-dihydro-3,3-dimethyl-13-(4-cyanophenyl)-2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione (4c), 3,4-dihydro-3,3-dimethyl-13-phenyl-2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione (4d), and 3,4-dihydro-13-(4-isopropylphenyl)-3,3-dimethyl-2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione (4e) have been elucidated from IR, NMR and mass spectral data.
Electric Literature of 14348-75-5, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 14348-75-5 is helpful to your research.
