What are the starting material in Doebner Miller reaction?
The Doebner–Miller reaction is the organic reaction of an aniline with α,β-unsaturated carbonyl compounds to form quinolines.
What is the right method of preparing quinoline?
Quinolines, an important class of potentially bioactive compounds, have been synthesized by treatment of o-aminoaryl ketones and carbonyl compound utilizing niobium (V) chloride (NbCl5) as an available and inexpensive catalyst.
Where is quinoline from?
Quinoline alkaloids are biogenetically derived from anthranilic acid and occur mainly in Rutaceous plants (14). These alkaloids were encountered in Sri Lankan plants of the families Annonaceae and Moraceae, in addition to the Rutaceae.
Why does electrophilic substitution reaction in quinoline take place at 5 and 8 position?
This is because the lone pair of nitrogen doesn’t take place in resonance with the benzene ring in pyridine. Hence in Friedel Crafts reaction when the Lewis acid is added it accepts the lone pair of the nitrogen atom. And thus forming an addition product. And as a result the electrophile is unable to generate.
What is the chemical name of quinoline?

What is quinoline found in?
Which is reactive position for electrophilic substitution reaction in quinoline?
Quinoline undergoes electrophilic substitution reactions only under vigorous conditions. Substitution occurs at C-8 and C-5.
Is chloroquine a quinoline?
The quinoline-containing antimalarial drugs, chloroquine, quinine and mefloquine, are a vital part of our chemotherapeutic armoury against malaria.
How is chloroquine synthesized?
Chloroquine, 7-chloro-4-(4-diethylamino-1-methylbutylamino)-quinoline (37.1. 3), is made by reacting 4,7-dichloroquinoline (37.1. 1.1) with 4-diethylamino-1-methylbutylamine (37.1.
