Khaleghi Abbasabadi, Masoud;Azarifar, Davood research published ã?β-Alanine-functionalized magnetic graphene oxide quantum dots: an efficient and recyclable heterogeneous basic catalyst for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione and 2,3-dihydroquinazolin-4(1H)-one derivativesã? the research content is summarized as follows. In this research, a novel synthesis of magnetic β-alanine-functionalized-graphene oxide quantum dots Fe3O4@GOQDs-N-(β-alanine) as a recyclable and eco-friendly heterogeneous nanocatalyst was reported. The catalytic efficiency of these nanosheets was explored as a basic catalyst for a one-pot three-component synthesis of various 1H-pyrazolo[1,2-b]phthalazine-5,10-dione I (Ar = 2,3-dichlorophenyl, 4-methoxyphenyl, pyridin-4-yl, etc.) and 2,3-dihydroquinazolin-4(1H)-one derivatives II (R = Me, MeO, Cl; R1 = H, Cl; R2 = H, Cl; R3 = H, Me, MeO, F, Cl). The reactions proceeded smoothly under mild and green conditions to afford the respected products I and II in excellent yields. The structure of this newly fabricated catalyst was successfully confirmed by different anal. techniques such as Fourier transform IR spectroscopy, X-ray diffraction, field emission-SEM, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, vibrating sample magnetometry, and thermogravimetric anal. The stability and recyclability of the catalyst were examined by performing the model reaction in six consecutive runs. The recovered catalyst from the first run was directly used for the next runs with no significant loss of catalytic activity.
6334-18-5, 2,3-Dichlorobenzaldehyde(2,3-DBA)is a useful research compound. Its molecular formula is C7H4Cl2O and its molecular weight is 175.01 g/mol. The purity is usually 95%.
2,3-DBA is an organic compound that is used as a synthetic intermediate in the preparation of other chemicals. It is prepared by reacting 2-chloroacetophenone with hydrochloric acid and sodium carbonate in a reaction vessel. The product can be purified through fractional distillation or crystallization. The optical properties of 2,3-DBA are determined by its dipole moment and the substituents attached to the methylene group. Molecular modeling studies have shown that felodipine can bind to 2,3-DBA through its active methylene group. The reaction products between sulfadiazine and 2,3-DBA are pyridinedicarboxylic acid and 3-chlorobenzaldehyde.
2,3-DBA is part of a group of Benzaldehyde (B119740) derivatives that exhibit activity against Mycobacterium tuberculosis, the bacteria responsible for causing tuberculosis in humans. 2,3-DBA is also used as a reagent to synthesize (E)-2-(2-arylhydrazinyl)quinoxalines, compounds that have potent anticancer activity., Formula: C7H4Cl2O
