Two mutually complementary synthetic approaches towards 3-substituted 3,4-disubstituted and 1-(2-pyridyl)-substituted isoquinolines [PDF]

Chimica Techno Acta, 2018
Two mutually complementary synthetic approaches towards 3- and 3,4-disubstituted 1-(2-pyridyl) isoquinolines were studied. The aryne-based method was successfully used for the obtaining of the corresponding the 3-cyano-1-(2-pyridyl)isoquinolines in one ...

isoquinolines [PDF]

, 2022
A variety of thieno[3,2-f]isoquinolines were prepared by combination of Pd catalysed cross-coupling reactions with Brønsted acid mediated cycloisomerisations. The reactions tolerate various functional groups and proceed with high selectivity. In addition,

Nitrogen atom insertion into indenes to access isoquinolines [PDF]

, 2022
We report a convenient protocol for a nitrogen atom insertion into indenes to afford isoquinolines. The reaction uses a combination of commercially available (diacetoxy¬iodo)benzene (PIDA) and ammonium carbamate to furnish a wide range of isoquinolines ...

Oxidation and hydrogenation of benzo[g]isoquinolines

, 2020
The oxidation of methyl-substituted (in the pyridine and benzene rings) benzo[g]isoquinolines to substituted 2-azaanthraquinones was realized. It was established that the pyridine ring is partially reduced to give 1,2,3,4-tetrahydrobenzo[g]isoquinolines ...

A Concise Total Synthesis of the Fungal Isoquinoline Alkaloid TMC-120B

Molecules, 2022
Recent reports of antiepileptic activity of the fungal alkaloid TMC-120B have renewed the interest in this natural product. Previous total syntheses of TMC-120B comprise many steps and have low overall yields (11–17 steps, 1.5–2.9% yield).

Nitration of Pyrrolo[2,1‑a]isoquinolines

, 2023
We have successfully modified a series of pyrrolo[2,1-a]isoquinolines via direct nitration under mild reaction conditions. Easily accessible nitrates including CAN, Cu(NO3)2·H2O, and Fe(NO3)3·9H2O all can serve as effective nitrating reagents for ...
