Spiro-Bicyclic Bisborane Catalysts for Metal-Free Chemoselective and Enantioselective Hydrogenation of Quinolines.

Angewandte Chemie, 2019
A new series of spiro-bicyclic bisborane catalysts has been prepared by means of hydroboration reactions of C2 -symmetric spiro-bicyclic dienes with HB(C6 F5 )2 and HB(p-C6 F4 H)2 .

Green synthesis of silver nanoparticles using green alga (Chlorella vulgaris) and its application for synthesis of quinolines derivatives

Synthetic Communications, 2019
Nanoparticles have been used century ago but have regained their importance in recent years being simple, ecofriendly, pollutant free, nontoxic, low-cost approach, and due good atom economy.

Quinoline-Annulated Porphyrins

Organic Letters, 2011
Porphyrin-2,3-dione mono- and dioximes were used as starting materials for the efficient syntheses of mono- and bis-quinoline-annulated porphyrins and their corresponding N-oxides. Owing to an extended π-system, these novel porphyrinoid chromophores show significantly red-shifted UV-vis spectra compared to the parent porphyrins.

Friedländer quinoline synthesis

2009
Also known as the Friedlander condensation, it combines an α-amino aldehyde or ketone with another aldehyde or ketone with at least one methylene α adjacent to the carbonyl to furnish a substituted quinoline. The reaction can be promoted by either acid, base, or heat.
