Bio-Fe3O4-MNPs catalyzed green synthesis of pyrrolo[2,1-a]isoquinoline derivatives using isoquinolium bromide salts: study of antioxidant activity

In this research, a novel, one-pot, efficient procedure with high yield for the synthesis of pyrrolo[2,1-a]isoquinoline derivatives using multi-component reaction of isoquinoline, alkyl bromides, and triphenylphosphine in the presence of Fe3O4-MNPs as catalyst under solvent-free conditions at room temperature is investigated. This study highlights an easy, simple, rapid, and clean method for the preparation of pyrrolo[2,1-a]isoquinoline derivatives. The Fe3O4-MNPs in these reactions were produced employing a green procedure by reduction of ferric chloride solution with pomegranate peel water extract. Additionally, antioxidant activity was studied for the some newly synthesized compounds such as 5a-5d using the DPPH radical trapping and reducing potential of ferric ion experiments and comparing the results with the results of synthetic antioxidants (2-tert-butylhydroquinone, TBHQ; butylated hydroxytoluene, BHT). As a result, compounds 5a-5d show trace DPPH radical trapping and excellent reducing power of ferric ion.

HETEROAROMATIC N-OXIDE REARRANGEMENTS – REINVESTIGATION OF 1,3 TOSYLOXY MIGRATION IN THE REACTION OF ISOQUINOLINE N-OXIDE WITH TOSYL CHLORIDE

Isoquinoline N-oxide (2) reacts with O-18-enriched tosyl chloride to furnish O-18-labeled 4-tosyloxy-isoquinoline (4), which was assessed for oxygen isotopic enrichment by NMR and mass spectrometry. The 30-45% O-18 incorporation at the bridging oxygen is inconsistent with a high level of the intramolecular tight-ion-pair (”sliding”) mechanism. A combination of two intramolecular mechanisms is probably operative.

A series of novel blue-light-emitting 2H-imidazo[5,1-a]isoquinolinium chloride derivatives were synthesized by the reaction of isoquinoline with trifluoroacetimidoyl chlorides and isocyanides in dry CH2Cl2 in excellent yields. Fluorescence studies showed that the compounds absorb UV radiation and then emit blue light at about 481 nm with moderate to good fluorescence quantum yields. These compounds also showed high Stokes shifts, and can be used to develop ultrasensitive fluorescent molecular probes to study a variety of biological events and processes.

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.

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.
