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 ...

Synthesis of 1H-Pyrrolo[3,2-g]isoquinoline Derivatives as Ligands Targeting Haspin Kinase [PDF]

Molecules
A new series of 1H-pyrrolo[3,2-g]isoquinolines, diversely substituted at the 3-position either by a heteroaromatic scaffold or by propionate/acrylate side chains, were synthesized and evaluated as Haspin kinase inhibitors.

Photoredox catalytic asymmetric dearomative [3 + 2] cycloaddition of isoquinolines with enones [PDF]

Nature Communications
Asymmetric dearomative photocycloaddition has emerged as a transformative strategy for the enantioselective construction of complex three-dimensional molecular architectures from simple planar aromatic precursors. While significant progress has been made

Photoinduced polarity-mismatched transformations of isoquinolines into naphthalenes [PDF]

Nature Communications
Isosteric replacement is an important strategy for lead optimization in drug-development paradigms. However, it is usually restricted to cost- and labor-intensive de novo syntheses.

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,

Synthesis of 5,6-Dihydropyrazolo[5,1-a]isoquinolines through Tandem Reaction of C,N-Cyclic Azomethine Imines with α,β-Unsaturated Ketones

Molecules, 2023
An innovative and efficient approach has been developed for the synthesis of 5,6-dihydropyrazolo[5,1-a]isoquinolines. This one-pot tandem reaction involves the reaction of C,N-cyclic azomethine imines with α,β-unsaturated ketones, using K2CO3 as the base
