Nucleophilic substitution on 2-monosubstituted quinoxalines giving 2,3-disubstituted quinoxalines: Investigating the effect of the 2-Substituent

An investigation on the effect of substituent at the 2-position of mono-substituted quinoxalines in the synthesis of di-substituted quinoxaline derivatives via nucleophilic substitution reactions, is reported. Di-substituted quinoxalines bearing aryl-Alky

Efficient Pd-catalyzed coupling of tautomerizable heterocycles with terminal alkynes via C-OH bond activation using PyBrOP

The direct alkynylation of tautomerizable heterocylcles is described via a two-step process involving in situ C-OH activation with bromotripyrrolidinophosphonium hexafluorophosphate (PyBrOP) followed by Sonogashira coupling with a wide range of alkyl or a

Direct dehydrative cross-coupling of tautomerizable heterocycles with alkynes via Pd/Cu-catalyzed phosphonium coupling

The first chemoselective direct dehydrative cross-coupling of tautomerizable heterocycles with alkynes has been achieved via C-H/C-OH bond activations with direct C(sp2)-C(sp) bond formation, which is in line with ideal synthesis using readily

Direct introduction of acetylene moieties into azines by SNH methodology

The N-oxides of azines 1a-g react with lithium and/or potassium acetylides to give the corresponding ethynylazines 2a-g. Reaction with lithium acetylide requires subsequent acylation of the intermediate anionic adduct for rearomatization whereas in the case of potassium acetylide, auto-aromatization takes place.

Palladium-catalyzed coupling reaction of haloheteroaromatic compounds in water

Palladium-catalyzed coupling reaction of π-deficient heteroaromatic halide in water was accomplished with excellent to good yields without any side reactions such as hydrolysis.

Synthesis of thieno[2,3-b]quinoxalines from 2-haloquinoxalines

Thieno[2,3-b]quinoxalines were synthesized from 2-haloquinoxalines using palladium catalyst. The coupling of latter with alkynes and addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced was described. The resulting dibromid

Alkynyl- and Dialkynyl-quinoxalines. Synthesis of Condensed Quinoxalines

Condensation of 2-chloro- and 2,3-dichloroquinoxalines with alk-1-ynes in the presence of bis(triphenylphosphine)palladium(II) dichloride and copper(I) iodide gives mono- and di-alkynylquinoxalines.Addition of amines to these products gives stable enamines; hydration gives 2'-oxoalkyl compounds which exist predominantly in the intramolecularly hydrogen-bonded enol form.Condensation of the alkynylquinoxalines with diethyl sodiomalonate, and related compounds, yields pyridoquinoxalin-4-one derivatives. 2-Alkynyl-3-chloroquinoxalines are intermediates for convenient syntheses of pyrroloquinoxalines.
