Efficient Synthesis of Pyrrolo[2,1-a]isoquinoline and Pyrrolo[1,2-a]quinoline Derivatives via One-pot Two-step Metal-catalyzed Three-component Reactions

A sequential one-pot two-step reaction for efficient synthesis of pyrrolo[2,1-a]isoquinoline and pyrrolo[1,2-a]quinoline derivatives in good yields has been successfully developed. The reaction included firstly Cu-catalyzed three-component reaction of isoquinoline (quinoline), acetylenedicarboxylate and alkynylbenzene and then Pd-catalyzed intramolecular C(sp)-C(sp2) coupling reaction of initially formed 1-alkenyl-2-alkynyl-1,2-dihydroisoquinoline (1,2-dihydroquinoline).

CONSTRUCTION OF A DNA-PROBE TO DETECT ISOQUINOLINE-DEGRADING BACTERIA

To facilitate the cloning of DNA encoding isoquinoline degradation an assay was developed that allowed the rapid visual scoring of the isoquinoline degradation phenotype of single colonies. Transposon mutagenesis of one of the isolates, Comamonas acidovorans IQ3, was performed using Tn5, and nine Isq(-) mutants deficient in the ability to utilise isoquinoline as the sole nitrogen source were isolated. These mutants were also incapable of utilising the first metabolite of the isoquinoline degradation pathway, 1-hydroxyisoquinoline, as the sole carbon source. For each Isq(-) mutant, the EcoRI fragment containing the Tn5 insertion was cloned into pBR322. Restriction and Southern analyses of the cloned DNA revealed that of the nine Isq(-) mutants, six contained Tn5 insertions in a common 8.9-kb EcoRI fragment derived from the wild type, C. acidovorans IQ3. The cloned DNA thought to be involved in the degradation of isoquinoline proved to be specific when used as a probe in colony hybridization to some bacteria possessing the ability to degrade isoquinoline.

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.

Isoquinoline skeleton synthesis via chelation-assisted C-H activation

Transition-metal-catalyzed isoquinoline synthesis that profits from the strategy of chelation-assisted C-H activation has flourished over the past decade. By virtue of the directed C-H bond cleavage of imines, amines, amidines, oximes, hydroximoyl halides, hydrazones, or azines, diverse isoquinoline derivatives have been accessed from alkynes, conjugated dienes, or diazo compounds under the catalysis of rhodium, ruthenium, palladium, nickel, or manganese. This digest summarizes the annulation reactions via chelation-assisted C-H activation leading to isoquinolines, isoquinolinium salts, or isoquinoline N-oxides. (C) 2014 The Authors.

Direct 1,4-difunctionalization of isoquinoline

The synthesis of 1,4-disubstituted isoquinoline derivatives was achieved in one step starting from isoquinoline. The process involved a nucleophilic addition in 1-position followed by an electrophilic trapping in 4-position. Interesting features were noted when C2Cl6 was used as the electrophile since different compounds could be isolated selectively only by adjusting the reaction parameters. (C) 2009 Elsevier Ltd.

Synthesis and reactivity of some imidazo-, triazolo- and tetrazolo-isoquinoline derivatives

1-Acetylimino-3-methyl-1H-isochromene-4-carbonitrile, 1, reacts with glycine ethyl ester under basic conditions to give an imidazo[2,1-a]isoquinoline derivative, while reaction with hydrazine hydrate in 1,4-dioxane, with further chemistry, provides access to [1,2,4]triazolo[5,1-a]isoquinoline, [1,2,4]triazolo[3,4a]isoquinoline and tetrazolo[5,1-a]isoquinoline analogs. Benzene ring nitration and radical bromination of substituent methyl groups were investigated in the four tricycles, with some different positional reactivities being found. Two bromomethyl derivatives so produced were oxidised; ethyl 2-bromomethyl-6-cyano-5-methylimidazo[2,1-a]isoquinoline-3-carboxylate gave the anticipated ethyl 6-cyano-2-formyl-5-methylimidazo[2,1-a]isoquinoline-3-carboxylate (which reacted further with hydrazine to form a new system, 8,9-dihydro-6-methyl-8-oxopyridazino[4′,5′:4,5]imidazo[2,1-a]isoquinoline-5-carbonitrile), while 5-bromomethyl-2-methyl[1,2,4]triazolo[5,1-a]isoquinoline-6-carbonitrile unexpectedly gave directly another new system, 5,6-dihydro-5-hydroxy-2-methyl-7H-pyrrolo[3,4-c][1,2,4]triazolo[5,1-a]isoquinolin-7-one.
