Zaharani, Lia;Ghaffari Khaligh, Nader;Gorjian, Hayede;Rafie Johan, Mohd research published 《 4,4′-trimethylenedipiperidine as a nitrogen heterocycle solvent and/or catalyst: liquid phase tandem Knoevenagel-Michael condensation》, the research content is summarized as follows. Liquid phase tandem Knoevenagel-Michael condensation of various aromatic and heteroaromatic aldehydes with barbituric acid or 2-thiobarbituric acid and malononitrile was studied in a one-pot three-component reaction. For the first time, TMDP was employed as a safe and efficient solvent and/or catalyst in the liquid and aqueous ethanol medium, resp., for the practical and eco-friendly Knoevenagel-Michael condensation. The reactions were carried out by using greener procedures, including (a) the use of TMDP as an N-heterocycle organocatalyst in a green medium including water and ethanol (1:1 volume/volume) at reflux temperature, and (b) the use of TMDP as a dual solvent-catalyst at 65°C in the absence of any solvent. High to excellent yields of the desired pyrano[2,3-d] pyrimidinones were obtained under the two earlier mentioned conditions. The current methodologies have advantages, including (a) avoiding hazardous, toxic, volatile, and flammable materials and solvents, (b) avoiding tedious processes, harsh conditions, and multiple steps for the preparation of catalysts, (c) using a less toxic and noncorrosive catalyst, (d) minimizing hazardous waste generation and simple workup process, and (e) high recyclability of TMDP. Another important result of this work is that the TMDP can be a promising alternative for toxic, volatile, and flammable base reagents such as piperidine and triethylamine in liquid phase organic syntheses owing to its unique properties such as being less toxic, nonflammable, and nonvolatile, and having a low m.p., broad liquid range temperature, high thermal stability, and safe handling and storage.
Reference of 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., 6334-18-5.
