Oxidative decarbonylative coupling of aliphatic aldehydes with methacryloyl benzamides to generate isoquinoline-1,3(2H,4H)-diones

Alkyl-substituted isoquinoline-1,3(2H,4H)-diones were prepared by decarbonylative coupling of N-alkyl-N-methacryloylbenzamides and aliphatic aldehydes under metal-free conditions. The reaction undergoes subsequent decarbonylation, radical addition and cyclization processes with aliphatic aldehydes as the cheap and abundant alkyl radical source. This procedure offers a complementary approach to the convenient generation of alkyl-substituted isoquinoline-1,3(2H,4H)-diones.

Cholinesterase inhibitory isoquinoline alkaloids from Corydalis mucronifera

Eight previously undescribed isoquinoline alkaloids, mucroniferanines H-M, together with 16 known isoquinoline alkaloids, were isolated from Corydalis mucronifera Maxim.. The structures of the previously undescribed compounds were elucidated by interpretation of 1D and 2D NMR spectroscopic and HAMS data, and their absolute configurations were established by computational electronic circular dichroism (ECD) calculations and X-ray diffraction data. Mucroniferanine L is reported as the first natural amide bond linked isoquinoline alkaloid dimer. The isolated compounds were evaluated for AChE and BuChE inhibitory activities and mucroniferanine H showed significant activities with IC50 values of 2.31 mu M and 36.71 mu M, respectively.

Isoquinoline N-Oxide Synthesis under Pd-Catalysed C-H Activation/Annulation Processes

An oxime directed C-H activation-annulation reaction for the selective synthesis of a range of isoquinoline N-oxides has been developed. Under palladium-catalyzed acid-assisted conditions, the reaction undergoes concerted metallation deprotonation followed by carbopalladation and transmetallation to give polysubstituted isoquinoline N-oxides in moderate to good yields.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 21806-61-1, in my other articles.

Genetic aspects of the relationship between isoquinoline alkaloids and mineral elements in greater Celandine (Chelidonium majus L.)

Interrelations between the total content of isoquinoline alkaloids, the concentrations of quaternary protoberberines and benzophenanthridines, and the amount of K, Cu, Co, Al, Ba, and Zn in aerial parts of individual celandine plants were revealed, within a single cenopopulation, using correlation analysis and regression analysis. Mathematical models describing the regulation of isoquinoline metabolism by some of the mineral elements were obtained in analytical form. The results suggest that this process is genetically determined.

Tetra-mu(2)-acetato-kappa O-8:O ‘-bis[(isoquinoline-kappa N)copper(II)]

In the crystal structure of the title compound, [Cu-2(CH3-COO)(4)(C9H7N)(2)], the Cu-II cation is coordinated by four acetate anions and one isoquinoline molecule in a distorted square-pyramidal geometry; the Cu-II cation is 0.1681 (6) angstrom from the basal coordination plane formed by the four O atoms. Each acetate anion bridges two Cu-II cations to form the centrosymmetric dinuclear complex. Within the dinuclear molecule, the Cu center dot center dot center dot Cu separation is 2.6459 (4) angstrom. A parallel arrangement of isoquinoline ligands of adjacent complexes is observed in the crystal structure; the face-to-face distance of 3.610 (10) angstrom suggests there is no pi-pi stacking between isoquinoline ring systems.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Isoquinoline

Isoquinoline, C9H7N, is a ligand which is used as a complexing agent for different metals. In order to compare geometric features of free isoquinoline and isoquinoline as a complexing ligand, we determined its crystal structure. Regrettably, the molecule is located on a centre of inversion and is therefore disordered; it is also isostructural with naphthalene. By refinement experiments and packing considerations, we were able to discard the possibility of fourfold disorder, which has been found for several beta-substituted naphthalene compounds, and performed the structure determination employing a model of twofold disorder.

CRYSTAL-STRUCTURE OF ISOQUINOLINE – PICRIC ACID COMPLEX

The crystal structure of the isoquinoline:picric acid complex (C9H7N . C6H3N3O7) was determined by means of X-ray crystal analysis. A proton of the hydroxyl group of picric acid was transferred to the nitrogen atom of the isoquinoline molecule in the complex. Isoquinoline and picric acid molecules are arranged alternately along the b-axis, making their molecular planes parallel to each other in the crystal. They overlap each other, and isoquinoline picrate is formed through both ionic interaction and pi-bonding.
