Facile Access to Benzothiazole-containing Pyrrolo[1,2-a]quinolines and Pyrrolo[2,1-a]isoquinolines via Nitrogen Ylides

Quinoline and isoquinoline react with 2-(bromoacetyl)benzothiazole (1) in dry benzene to give the corresponding quinolinium and isoquinolinium salts 2 and 10 which undergo base-mediated [3+2] 1,3-dipolar cycloaddition with some acetylene and ethylene derivatives to give the corresponding benzothiazoic-containing pyrrolo[1,2-a]quinoline and pyrrolo[2,1 -a]isoquinoline derivatives.

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 27655-40-9, in my other articles.

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.

Electronic Spectra of Gas-Phase Polycyclic Aromatic Nitrogen Heterocycle Cations: Isoquinoline(+) and Quinoline(+)

Electronic spectra of the gas-phase isoquinoline(+)-Ar and quinoline(+)-Ar complexes are recorded using photodissociation spectroscopy by monitoring the Ar loss channel. The D-3 <- D-0 and D-4 <- D-0 band origins for isoquinoline(+)-Ar are observed at 15245 +/- 15 cm(-1) and 21960 +/- 15 cm(-1), respectively, whereas for quinoline(+)-Ar they appear at 16050 +/- 15 cm(-1) and 21955 +/- 15 cm(-1), respectively. Strong vibronic progressions for the D-3 <- D-0 band systems of both isoquinoline(+)-Ar and quinoline(+)-Ar are modeled and assigned in terms of ring deformation and carbon carbon stretch vibrational modes using time-dependent density functional theory calculations in conjunction with Franck-Condon simulations. The properties of the isoquinoline(+) and quinoline(+) molecules are compared with those of the isoelectronic naphthalene(+) molecule. The existence of strong progressions in the visible spectra of isoquinoline(+)-Ar and quinoline(+)-Ar suggests that the corresponding isoquinoline(+) and quinoline(+) molecular cations are unlikely to be responsible for diffuse interstellar bands.

Isoquinoline alkaloids isolated from three Guatteria species

The chemical investigation of the aerial parts of Guatteria ferruginea collected in the National Park of Serra dos Orgaos, Teresopolis, Brazil and of Guatteria latifolia and Guatteria sellowiana collected in the National Park of Itatiaia, Itatiaia, Brazil resulted in the isolation and identification of six isoquinoline alkaloids, two aporphine alkaloids 3-hydroxy-nornuciferine (1), nornuciferine (2) and four oxoaporphine alkaloids lysicamine (3), isomoschatoline (4), liriodenine (5) and O-methylmoschatoline (6). The isoquinoline alkaloids were found in the species G. ferruginea, G. latifolia and G. sellowiana for the first time and they support the taxonomic position within the genus Guatteria. Isoquinoline alkaloids (5-6) can be considered chemotaxonomic markers of the subfamily Annonoideae. (C) 2017 Elsevier Ltd. All rights reserved.

N-OXIDATION OF QUINOLINE AND ISOQUINOLINE BY CUNNINGHAMELLA-ELEGANS

Cultures of Cunninghamella elegans were grown for 7 days in liquid Sabouraud medium containing 1.9 mM quinoline or isoquinoline. The spent culture media were extracted with ethyl acetate; metabolites were purified by high-performance liquid chromatography (HPLC) and thin-layer chromatography. The major metabolite produced from each compound was identified by the HPLC elution time, ultraviolet/visible absorption spectrum, and mass spectrum. Under similar conditions, approximately 65% of the added quinoline and 3% of the added isoquinoline were metabolized to quinoline N-oxide and isoquinoline N-oxide, respectively.

Determination of isoquinoline alkaloids in Thalictrum herbal drugs by non-aqueous capillary electrophoresis

A rapid non-aqueous capillary electrophoresis method has been developed for the separation and determination, within 14 min, of eight isoquinoline alkaloids (berberine, palmatine, jatrorrhizine, (+)-tetrandrine, berbamine, thalifaricine, northalfine, and thalistine) in seventeen samples of the herbal drug thalictrum. A methanolic solution of sodium acetate (75 mm) and acetic acid (1 M) was found to be the optimum running buffer for the separation. Thalictrum Atriplex Finet et Gagep (T. AFG) was selected for further study, including investigation of recovery and precision, because this preparation contained all the isoquinoline alkaloids tested. Calibration curves were highly linear over a 20-fold concentration range and detection limits for all eight alkaloids were in the range 0.42-3.04 mug mL(-1).
