Abstract:
o-Phenylenediammines and o-aminophenols were reacted with α-oxodithioesters in a highly regioselective fashion to give 2-methylthio-3-aryl/heteroarylquinoxalines and 2-acylbenzoxazoles in 55–94% and 45–86%, respectively, in the presence of p-toluene sulfonic acid catalyst. Control experiments involving reaction of aniline with a α-oxodithioester indicated that the thiocarbonyl group is more reactive than the carbonyl group. Based on this, probable mechanisms for the formation of quinoxalines and benzoxazoles are given. Biological targets of the quinoxalines and benzoxazoles were identified by

Abstract:
We have reported highly proficient, environmental benign, SiO2@PPA catalyzed protocol for the synthesis of 2, 3-diphenyl quinoxalines via condensation of ophenylene diamine with α-diketones. Surface modified silica with polyphosphuric acid offered outstanding catalytic efficiency at room temperature and it sustained up to fifth cycle. The methodology boasts a hassle-free catalyst preparation process, operates under energy-conserving conditions, yields a commendable (93-84%) output of the targeted moieties and exhibits catalyst recyclability. These appealing features position it as a superior a

Abstract:
This dissertation describes the density functional theory (DFT) computational modelling of reactions between organolithium nucleophiles and various substituted quinoxalines. These reactions result in the functionalisation of the C (sp2)–H bond, thus substituting the sigma-hydrogen. The reactions are known as nucleophilic substitution of hydrogen (SNH) and are used by experimental chemists to form new C–C bonds. The SNH reactions are very important in various industries, e.g. in designing and manufacturing of pharmaceuticals. Quinoxaline is widely used in medicinal chemistry due to its various

AbstractThe synthesis of pyrazino[1,2-a]indoles and related indolo[1,2-a]quinoxalines and pyrido[2′,1′:3,4]pyrazino[1,2-a]indol-5-ium salts are reviewed in this chapter. The most common routes to pyrazino[1,2-a]indoles involve cyclization of indole derivatives containing a formyl, keto, ester, or nitrile function at the 2-position. Indolo[1,2-a]quinoxalines are most readily accessed via cyclization of 1-(aryl)-1H-indoles, where the aryl group is substituted at the 2-position by either amino, iodo, or nitro functionality.
