An efficient method for Ir-catalyzed ligand free ortho borylation of arenes (such as, 2-phenoxypyridines, 2-anilinopyridines, benzylamines, benzylpiperazines, benzylmorpholines, benzylpyrrolidine, benzylpiperidines, benzylazepanes, α-amino acid derivatives, aminophenylethane derivatives, and other important scaffolds) and pharmaceuticals has been developed. The reaction underwent via an interesting mechanistic pathway, as revealed by the detailed mechanistic investigations by using kinetic isotope studies and DFT calculations The catalytic cycle is found to involve the intermediacy of an Ir-boryl complex where the substrate C-H activation is the turnover determining step, intriguingly without any appreciable primary KIE. The method displays a broad range of substrate scope and functional group tolerance. Numerous late-stage borylation of various important mols. and drugs were achieved using this developed strategy. The borylated compounds were further converted into more valuable functionalities. Moreover, utilizing the benefit of the B-N intramol. interaction of the mono borylated compounds, an operationally simple method has been developed for the selective diborylation of 2-phenoxypyridines and numerous functionalized arenes. Furthermore, the synthetic utility has been showcased with the removal of the pyridyl directing group from the borylated product to achieve ortho borylated phenol along with the ipso-borylation for the preparation of 1,2-diborylated benzene.
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
