Heterocyclic systems containing S/N regioselective nucleophilic competition: facile synthesis, antitubercular and antimicrobial activity of thiohydantoins and iminothiazolidinones containing the benzo[b]thiophene moiety [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
The required compounds N-aryl-N'-(3-chloro-2-benzo[b]thenoyl)–thioureas 1a–k were prepared by condensing 3-chloro-2-benzo[b]thenoyl chloride with different arylamines using ammonium thiocyanate, which in turn when treated with chloroacetic acid, yielded ...

Investigation of Novel Isatinylhydantoin Derivatives as Potential Anti‐Kinetoplastid Agents

open access: yesChemMedChem, Volume 20, Issue 1, January 2, 2025.
A series of isatinylhydantoin derivatives were synthesized and investigated for antileishmanial and antitrypanosomal activities in vitro and in vivo. The derivative 5 was identified with higher leishmanicidal activity than the clinical drug amphotericin B while 4b was uncovered as in vitro trypanocidal hit against T. congolense parasite.

1,2‐Diaza‐1,3‐Dienes as a Multifaceted Synthons for the Synthesis of Heterocycles: A Fifteen‐Years Update

open access: yesEuropean Journal of Organic Chemistry, Volume 27, Issue 44, November 25, 2024.
1,2‐Diaza‐1,3‐butadienes, also called azoalkenes, have received considerable attention as key synthons for constructing various heterocyclic scaffolds. This minireview summarizes the contribution of our group in this field over the period from 2009 to the present, focusing on the role of the azoene building block in forming the heterocyclic structures.
