Large-scale solvent-free chlorination of hydroxy-pyrimidines,-pyridines,- pyrazines and-amides using equimolar POCl3

Chlorination with equimolar POCl3 can be efficiently achieved not only for hydroxypyrimidines, but also for many other substrates such as 2-hydroxy-pyridines,-quinoxalines, or even-amides. The procedure is solvent-free and involves heating in a sealed reactor at high temperatures using one equivalent of pyridine as base. It is suitable for large scale (multigram) batch preparations.

Synthesis of thieno[2,3-b]quinoxalines and pyrrolo[1,2-a]-quinoxalines from 2-haloquinoxalines

The palladium(0)-catalysed coupling of 2-haloquinoxalines with functionally substituted alkynes, addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced and then reaction of the resulting dibromides with disodium trithiocarbonate produced 2-hydroxymethyl- and 2-(diethoxymethyl)thieno[2,3-b]quinoxalines. Addition of bromine to some 6-substituted-2-(3,3-diethoxypropyn-1-yl)quinoxalines gave pyrrolo[1,2-a]quinoxalines. Treatment of a 3-(1,2-dibromoalkenyl)quinoline, a 3-(1,2-dibromoalkenyl)pyrazine, and a 5-(1,2-dibromoalkenyl)-pyrimidine with disodium trithiocarbonate failed to induce thiophene ring formation.

Antimicrobial evaluation and action mechanism of chalcone derivatives containing quinoxaline moiety

Abstract: A series of chalcone derivatives containing quinoxaline moieties were synthesized, and their antibacterial activities were evaluated. Antibacterial bioassays indicated that some of the compounds exhibited significant antibacterial activity against Xanthomonas axonopodis pv. Citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Ralstonia solanacearum (Rs) at the concentrations of 50 or 100?mug/cm3. 50% effective concentration (EC50) values of (E)-3-(pyridin-2-yl)-1-[4-(quinoxalin-2-yloxy)phenyl]prop-2-en-1-one against Xac, Xoo, and Rs were 6.72, 15.17, and 9.29?mug/cm3, respectively, which were better than those of bismerthiazol (44.31, 42.46, and 62.36?mug/cm3, respectively). Scanning electron microscopy (SEM) was employed to analyze the mechanism of antibacterial action of that compound toward Xac. Graphical abstract: [Figure not available: see fulltext.].

M-Terphenyl-3,3?-dioxo-derived oxacalixaromatics: Synthesis, structure, and solvent encapsulation in the solid state

The synthesis of oxacalix[2]terphenylene[2]aromatics with enlarged macrocyclic holes by cyclooligomerization reaction of 5?-tert-butyl-(1, 1?:3?,1?-terphenyl)-3,3?-diol 1 with electron-deficient dihalogenated benzene and azaheterocycles is described. The structures of the macrocycles were characterized by NMR, HRMS spectroscopic and X-ray diffraction techniques. Single crystal X-ray analysis revealed that the terphenyl-3, 3?-dioxo unit incorporated in the oxacalix[4]aromatics scaffold can adopt all three possible conformations (I, II, III). The cis-conformational terphenyl-3,3?-dioxo (I and II) derived oxacalix[4]aromatics were found to adopt both chair and boat conformations, resulted in creation of molecular cavities capable of hosting solvent molecules of chloroform. The trans-conformational terphenyl-3,3?-dioxo (III) derived oxacalix[4]aromatics, however, adopt a twisted chair conformation with a narrow void space incapable of hosting any guest molecules.

The carbon signals of the 2-acylamino-4H-1,3,4-thiadiazino[5,6-b]quinoxalines 1a,b, 2-acylamino-4H-1,3,4-thiadiazino[5,6-b]quinoxaline 1,1-dioxides 2a,b, and 2-amino-4H-1,3,4-thiadiazino[5,6-b]quinoxaline 3 in deuteriodimethyl sulfoxide and in deuteriotrifluoroacetic acid were assigned by the nmr (HMBC, HMQC) spectroscopy. The comparison of the carbon chemical shifts in deuteriodimethyl sulfoxide with those in deuteriotrifluoroacetic acid clarified that compounds 1a, 1b, and 3 were deuterized at the N5-position in deuteriotrifluoroacetic acid, while the 1,1-dioxides 2a,b did not undergo the N5-deuteration in deuteriotrifluoroacetic acid.
