Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1008-89-5) here.

A new series of phosphine-free aurone-based α,β-unsaturated carbonyl-amino bidentate ligands I [R1 = 2-furanyl, Ph, 3-4-dimethoxyphenyl, etc.; R2 = Ph, 3-nitrophenyl, 1-naphthyl, etc.] were synthesized and characterized via different anal. techniques such as IR, 1H-NMR, 13C-NMR and mass spectrometry. Moreover, the structure of ligand I [R1 = 2-furanyl; R2 = 2-nitrophenyl] was also characterized by single-crystal X-ray diffraction. The synthesized ligands I with the PdCl2 salt showed excellent catalytic activity in the Suzuki-Miyaura, Mizoroki-Heck and Buchwald-Hartwig reactions. A broad range of substrates including heterocycles, chalcones and sterically hindered coupling partners were well tolerated in the developed protocol. Addnl., the metal complex formed in the catalytic cycle was characterized by 1H-NMR spectroscopy and mass spectrometry.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Dipyrrinato-Iridium(III) Complexes for Application in Photodynamic Therapy and Antimicrobial Photodynamic Inactivation, published in 2021-04-11, which mentions a compound: 1008-89-5, mainly applied to dipyrrinato iridium complex preparation antimicrobial photodynamic inactivation therapy; crystal structure dipyrrinato iridium complex antimicrobial photodynamic inactivation therapy; mol structure dipyrrinato iridium complex; dipyrromethane oxidation chloroanil reagent; (dipyrrinato)iridium(III) complexes; antimicrobial photodynamic inactivation; dipyrrins; glycosylation; photodynamic therapy, Application of 1008-89-5.

The generation of bio-targetable photosensitizers is of utmost importance to the emerging field of photodynamic therapy and antimicrobial (photo-)therapy. A synthetic strategy is presented in which chelating dipyrrin moieties were used to enhance the known photoactivity of Ir(III) metal complexes. Formed complexes can thus be functionalized in a facile manner with a range of targeting groups at their chem. active reaction sites. Dipyrrins with N- and O-substituents afforded (dipy)iridium(III) complexes via complexation with the resp. Cp*-Ir(III) and ppy-Ir(III) precursors (dipy = dipyrrinato, Cp* = pentamethyl-η5-cyclopentadienyl, ppy = 2-phenylpyridyl). Similarly, electron-deficient [Ir(III)(dipy)(ppy)2] complexes could be used for post-functionalization, forming alkenyl, alkynyl and glyco-appended Ir(III) complexes. The phototoxic activity of these complexes was assessed in cellular and bacterial assays with and without light; the [Ir(III)(Cl)(Cp*)(dipy)] complexes and the glyco-substituted Ir(III) complexes showing particular promise as photomedicine candidates. Representative crystal structures of the complexes are also presented.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 132098-59-0, is researched, Molecular C19H18N2O2, about Chiral Calcium Complexes as Bronsted Base Catalysts for Asymmetric Addition of α-Amino Acid Derivatives to α,β-Unsaturated Carbonyl Compounds, the main research direction is Michael addition product enantioselective preparation; pyrrolidine enantioselective preparation; asym addition reaction cycloaddition amino acid unsaturated carbonyl compound; chiral calcium complex asym addition reaction cycloaddition.Computed Properties of C19H18N2O2.

A novel catalyst system based on complexes of calcium which promote the catalytic asym. 1,4-addition reactions and [3+2] cycloaddition reactions of α-amino acid derivatives with α,β-unsaturated carbonyl compounds have been developed. The reactions proceeded smoothly in the presence of 5-10 mol % of the chiral calcium catalyst to afford the desired adducts in high yields with high diastereo- and enantioselectivities. A wide range of α,β-unsaturated esters and amides were applicable, and other glycine and even dl-alanine derivatives reacted with several α,β-unsaturated carbonyl compounds to afford the corresponding substituted pyrrolidine derivatives in high yields with excellent diastereo- and enantioselectivities. In the reactions with dl-alanine derivatives, quaternary asym. carbons were constructed efficiently.

HPLC of Formula: 2208-59-5. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, is researched, Molecular C12H9N3, CAS is 2208-59-5, about Quantitative structure-activity relationships (QSAR) of smooth muscle relaxation and 2-substituted, benzimidazole derivatives. Author is Buyukbingol, Erdem; Safak, Cihat; Ozturk, Yusuf; Sahin, M. Fethi.

A series of the 2-substituted benzimidazole derivatives were tested for smooth muscle relaxation activity in rats. The pD2 and potency values were then analyzed in terms of hydrophobic (logP), electronic (dipole moment), and stereochem. (νw) factors by linear and multiple regression anal. The activity is depended parabolically on logP with the 2 other factors involved in the regression model. A correlation of pD2 with dipole moment was observed In all other model attempts the nonsignificant correlation led to suggest that mol. shape and size of the compounds would be unimportant in their smooth muscle relaxation activity in term of νw.

From this literature《Quantitative structure-activity relationships (QSAR) of smooth muscle relaxation and 2-substituted, benzimidazole derivatives》,we know some information about this compound(2208-59-5)HPLC of Formula: 2208-59-5, but this is not all information, there are many literatures related to this compound(2208-59-5).
