Close insight into the nature of intermolecular interactions in dihydropyrimidine-2(1H)-thione derivatives
(Royal Society of Chemistry, 2017-03)
The crystal structures of four 1-(R-phenyl)-4,4,6-trimethyl-3,4-dihydropyrimidine-2IJ1H)-thione derivatives [R = 2-chloro (1), 2,3-di-chloro (2), 2,4-di-methyl (3), and 4-methoxy (4)] were determined and analysis of their ...
An investigation of supramolecular synthons in 1,2,4-triazole-3(4H)-thione compounds. X-ray crystal structures, energetic and Hirshfeld surface analysis
(Elsevier Science, 2019-11)
A series of four closely related 1,2,4-triazole-3-thione (1-4) compounds was obtained by heterocyclization of thiosemicarbazides under basic catalytic conditions. The crystal structures of the 4-alkyl-5-(substituted-phen ...

Structure and toxicity of N-donor thionate Zn complexes
(Elsevier Science, 2022-04)
The reaction of thiosaccharin (thiosaccharin: the thione form of saccharin) and N-donor bases with Zn2+ yielded three new thionate complexes: [Zn(tsac)2(imidazole)2], [Zn(tsac)2(benzimidazole)2]·H2O and [Zn(tsac)2(2-meth ...
Ni-thiosaccharinate complexes: Synthesis, characterization and DFT studies. Biological properties as superoxide dismutase mimetics and as anti-carcinogenic agents
(Elsevier Science SA, 2019-08-01)
This report describes the synthesis and characterization of two nickel thiosaccharinate complexes, [Ni(tsac)2(PPh3)2] (1) and [Ni(tsac)2(dppe)]·CH3CN (2), where tsac = thiosaccharinate anion, PPh3 = triphenylphosphane and ...
In vitro Antifungal Activity of Dihydropyrimidinones/Thiones Against Candida albicans and Cryptococcus neoformans
(Bentham Science Publishers, 2019-12)
Background: Since the Monastrol discovery in 1999 as the first inhibitor of Eg5, functionalized dihydropyrimidinones/thiones (DHPMs) have emerged as prototypes for drug design in different targets. The present work aimed ...
Simple and ecofriendly synthesis of dihydropyrimidinones (thiones), dihydropyridines, and pyridines using 3-formylchromones as substrates assisted by a recyclable Preyssler heteropolyacid
(John Wiley & Sons Inc, 2016-09-13)
Several dihydropyrimidinones/thiones, 1,4-dihydropyridines, and pyridine derivatives were prepared in very good yields and purity values. The corresponding reactions were carried out by employing a bulk Preyssler heteropolyacid ...
A Domino Epoxide Ring-Opening Xanthate Migration Reaction: An Alternative Entry to Thiosugars
(Wiley VCH Verlag, 2018-12)
A sterereospecific and efficient synthesis of thiosugars derived from levoglucosenone and methyl α-d-glucopyranoside was developed by a domino epoxide ring opening- xanthate migration to afford 1,3-oxathiolane-2-thiones ...
Reversible S-S Bond Breaking and Formation in Disulfide-containing Dinuclear Complexes of Mn(I)
(Wiley VCH Verlag, 2001-12)
An isolated reaction intermediate in the desulfurization of thiones promoted by phosphanes is provided by the ylide derivative 3, which is obtained by thiophilic addition of PCy3 to 2. Complex 2 is formed from the ...
