Cyano-Sacrificial (Arylthio)arylamination of Quinoline and Isoquinoline N-Oxides Using N-(2-(Arylthio)aryl)cyanamides

A copper(I)-catalyzed regioselective arylthio-arylamination of quinoline and isoquinoline N-oxides has been achieved at the expense of a cyano (CN) group from N-(2-(arylthio)aryl)cyanamides. This reductive amination proceeds in one pot at 80 degrees C in the absence of any additives. This is a unique demonstration of aryl cyanamides serving as arylaminating agents on quinoline/isoquinoline N-oxides with concurrent autoreduction of N-oxide.

Synthesis of fused systems in the isoquinoline series: Oxazolo- and pyrrolo[3,2-c]isoquinolines

In order to synthesize the pyrrolo[3,2-c]isoquinoline structure, three different routes starting from readily available isoquinolines were tried. The ring closure reaction of a malonic derivative of 4-amino-3-bromoisoquinoline led to an oxazolo[3,2-c]isoquinoline instead of the target molecule. This latter was obtained via Sonagashira coupling reaction followed by ring closure under basic conditions. A study of the lithiation of the N-sulfonated pyrrolo[3,2-c]isoquinoline was undertaken. After optimization of the lithiation conditions, various 2-substituted pyrrolo[3,2-c]isoquinolines were obtained and their oxidation reactions studied.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 27655-40-9, you can contact me at any time and look forward to more communication. Formula: C9H7NO3S.

Synthesis of Antifungal Evaluation of 2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones

2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones and 2H-[1,2,3]triazolo[4,5-g]quinoline-4,9-diones were synthesized and tested for in vitro antifungal activity against pathogenic fungi. Many of those synthesized showed potent antifungal activity. Compounds 3a, 3b, 3g, and 3h completely inhibited the growth of all fungal species tested at the MIC level of 0.8-12.5 mu g/mL. The results suggest that 2H-[1,2,3]triazolo[4,5-g]-isoquinoline-4,9-diones could be antifungal agents.

Acetogenic isoquinoline alkaloids. Part 117 – First total synthesis of dioncophylline B, a 7,6 ‘-coupled naphthylisoquinoline alkaloid

The total synthesis of dioncophylline B (2), a naphthyl isoquinoline alkaloid with the rare 7,6′-coupling type and high antimalarial and fungicidal activities, is described. The key step of this convergent synthesis is the regioselective intermolecular biaryl coupling of its appropriately modified naphthalene and isoquinoline moieties, with MOM-functionalized oxygen substituents next to the coupling sites: The naphthalene moiety is activated by a directed ortho-metalation –> stannylation procedure, while the isoquinoline part is metalated and then brominated ortho to the MOM-protected oxygen function, thus allowing a Stille coupling to connect the two parts. The work constitutes the first synthesis of any 7,6’-coupled naphthylisoquinoline alkaloid.

Toxicity to PC12 cells of isoquinoline derivatives structurally related to 1-methyl-4phenyl-1,2,3,6-tetrahydropyridine

Isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine or 1-methyl-4-phenylpyridinium (MPP(+)) are inhibitors of mitochondrial function and substrates for the dopamine re-uptake system, but their neuronal toxicity is unclear, In this study, the effects of exposing PC12 cells to four isoquinoline derivatives (isoquinoline, N-methylisoquinolinium, 6,7-methylenedioxyisoquinoline and 1,2,3,4-tetrahydroisoquinoline) and MPP(+) (100-1000 mu M) were examined. All compounds exhibited concentration-dependent toxicity as determined by lactate dehydrogenase release, but none of the isoquinoline derivatives were more toxic than MPP(+). Cytotoxicity of these compounds appears to be directly correlated with their substrate affinity for the dopamine reuptake system, but not mitochondrial inhibition. Thus, the low toxicity of isoquinoline derivatives towards PC12 cells suggests that high concentrations of or prolonged exposure to these compounds may be necessary to cause the neurodegenerative changes related to Parkinson’s disease.
