Li, Xin-Ran;Li, Wan-Di;Wei, Wen-Ting;Fan, Juan;Liu, Zhong-Wen;Shi, Xian-Ying research published 《 Sequential Cobalt/Rhodium-Catalyzed Tandem Cyclization of Aromatic Aldehydes with Acrylates for Preparing 3-Substituted Phthalides in Oxygen Atmosphere and Neat Water》, the research content is summarized as follows. Metal-catalyzed C-H activation/tandem reactions of aromatic acids and functionalized alkenes is profound for constructing phthalide skeleton. However, most of these reactions employ stoichiometric amounts of metal additives and metal oxidants/toxic organic solvents. Herein, a sequential cobalt/rhodium-catalyzed tandem cyclization of aromatic aldehydes and acrylates for preparing 3-substituted phthalides in one pot has been described. This protocol features the use of water as a sustainable solvent and oxygen as the singular oxidant free of any additives. The use of aromatic aldehydes instead of aromatic acids as starting materials renders this route high atom economy, and the formation of water as a sole byproduct makes this process practical and environmentally benign.
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., Electric Literature of 6334-18-5
