Synthesis and antimicrobial activity of some new substituted quinoxalines

A number of new symmetrically and asymmetrically 2,3-disubstituted quinoxalines were synthesized through functionalization of 2,3-dichloroquinoxaline (2,3-DCQ) with a variety of sulfur and/or nitrogen nucleophiles. The structures of the obtained compounds were established based on their spectral data and elemental analysis. The antimicrobial activity for the prepared compounds was investigated against four bacterial species and two fungal strains. The symmetrically disubstituted quinoxalines 2, 3, 4, and 5 displayed the most significant antibacterial activity, while compounds 6a, 6b, and the pentacyclic compound 10 showed considerable antifungal activity. Furthermore, compounds 3f, 6b showed broad antimicrobial spectrum against most of the tested strains.

Microwave-assisted synthesis of indole-derivatives via cycloisomerization of 2-alkynylanilines in water without added catalysts, acids, or bases

An unprecedented green methodology is described for the preparation of differently substituted indoles via microwave-assisted cycloisomerization of 2-alkynylaniline derivatives in water. Moderate to good yields in the cyclization can be achieved for a variety of 2-aminoaryl alkynes. Reactions are run without any added metal catalyst, acid, or base, and do not take place by applying conventional heating.

Efficient diverse approach for quinoxaline-derived glycosylated and morphinylated analogs

Sulfanyl-glycosides have been synthesized by reaction of 2,3-dimercaptoquinoxaline (1) with acetohalo sugars in presence of base to give the thioglycosides-derived quinoxalines 5-7 and 9. Similarly, the acyclic analogs 23-26 were prepared by coupling of 1 with different acyclo-alkylating agents. The preparation of 3-morpholinyl-quinoxalines 10 and 11 allowed the synthesis of 3-glycosylsulfanyl-2-morpholinyl-quinoxalines 12-14 and 17 as well as the acyclic analogs 27-29. Microwave irradiation of the reactants turned out to be preferred over the conventional method for achieving the synthetic goals. This study made an available venue to the synthesis of diverse quinoxaline derivatives.

Iron-catalyzed Minisci acylation of N-heteroarenes with alpha-keto acids

An efficient and mild protocol has been developed for the Minisci acylation reactions of nitrogen-containing heteroarenes with alpha-keto acids. Distinct from the conventional Minisci acylation conditions, the chemistry was performed using non-noble metal Fe(II), instead of expensive Ag(I) salt, as catalyst. A wide range of substrates, including aliphatic or aromatic alpha-keto acids, as well as various N-heteroarenes, proved to be compatible with the protocol. Scale-up experiment also demonstrates the practicality of the approach.

New chromogenic and fluorescent probes for anion detection: Formation of a [2 + 2] supramolecular complex on addition of fluoride with positive homotropic cooperativity

(Figure Presented) Two new chromogenic and fluorescent probes for anions have been designed, synthesized, and characterized. These probes contain multiple hydrogen bonding donors including hydrazine, hydrazone, and hydroxyl functional groups for potential anion interacting sites. Despite the possible flexible structural framework due to the presence of sp3 carbon linkage, X-ray structure analysis of probe 2 displayed an essentially planar conformation in the solid state owing to strong crystal packing interactions comprising a combination of favorable pi-pi stacking effect and hydrogen bonding to cocrystallized CH3OH molecules. Both probes 1 and 2 display orange color in DMSO solution and show fairly weak fluorescence at room temperature. Binding studies revealed that both probes 1 and 2 show noticeable colorimetric and fluorescent responses only to F-, OAc-, and H2PO4- among the nine anions tested (F -, Cl-, Br-, I-, OAc-, H2PO4-, HSO4-, ClO 4-, and NO3-). The general trend of the sensitivity to anions follows the order of F- > OAc – > H2PO4- > Cl- > Br- ? I- ? HSO4- ? ClO4- ? NO3-. A 1:2 (probe to anion) binding stoichiometry was found for probe 1 with OAc- and H2PO4- and probe 2 with F-, OAc -, and H2PO4-. The binding isotherm of probe 1 to F- was found to be complicated with apparent multiple equilibria occurring in solution. The formation of an aggregated supramolecular complex upon addition of fluoride is proposed to rationalize the observed optical responses and is supported by ESI mass spectrometry and pulsed-field gradient NMR spectroscopy. Data analysis suggests that the binding of probe 1 to F- shows positive homotropic cooperativity.
