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 bioinformatics. It was found that quinoxalines have good binding affinity with human dual-specificity tyrosine-phosphorylation-regulated kinase 1A and benzoxazoles with human carboxylesterase.

Background: A series of novel substituted 2-mercaptoimidazoles was synthesised efficiently and in high yields using one-pot synthesis from m-hydroxyacetophenones. Methods: The structures of the newly synthesized compounds were established, their molecular activity was investigated against some bacteria and fungi were further validated using molecular docking study. Results: Reaction of o-hydroxyphenacylbromide (2) with substituted aniline and KSCN, in the presence of catalyst p-toluene sulfonic acid afforded 4(a-r) in good yield. The structure of compounds (4a-r) was confirmed by IR, NMR and MS. Conclusion: The compounds exhibited excellent antimicrobial potency against the tested microorganism.
