In this paper, a novel catalyst is introduced based on the immobilization of palladium on modified magnetic graphene oxide nanoparticles. The catalyst is characterized by several methods, including transmission electron microscopy, scanning electron microscopy, X-ray fluorescence, vibrating-sample magnetometer, Fourier transform-infrared and dynamic light scattering (DLS) analysis. The activity of the catalyst was investigated in the synthesis of 4(3H)-quinazolinones via Pd-catalyzed carbonylation-cyclization of N-(2-bromoaryl) benzimidamides by Mo (CO)6. The Mo (CO)6 is used as a carbon monoxide source for performing the reaction under mild conditions. The catalyst showed good reusability, and no change in activity was observed after 10?cycles of recovery.
Metal-free, one-pot oxidative conversion of aldehydes to primary thioamides in aqueous media

One-pot tandem reactions of a variety of aldehydes with aqueous ammonia, molecular iodine, and O,O-diethyl dithiophosphoric acid readily afford the corresponding primary thioamides. This is an inexpensive, practical, and metal-free way of accessing various thioamides from aldehydes in aqueous media. The pure products are obtained simply by filtration followed by successive washing with aqueous sodium thiosulfate and water. [Supplementary materials are available for this article.

Crystal landscape of primary aromatic thioamides
Eccles, Kevin S.,Morrison, Robin E.,Maguire, Anita R.,Lawrence, Simon E.
, p. 2753 - 2762 (2014/06/23)
The crystal landscape of a series of primary aromatic thioamides is described, displaying similar characteristic intermolecular hydrogen-bonding interactions in the solid state to those observed in their widely studied amide analogues, including R22(8) dimers and C(4) chains. In a number of cases, high Z′ values were observed in the structures. On the basis of the observed solid-state features, the thioamide functional group, which is a strong hydrogen-bond donor and moderate acceptor, offers considerable potential as a key moiety for crystal engineering.

Sulfonic acid functionalized nano γ-Al2O3 is easily prepared by the reaction of nano γ-Al2O3 with 1,3-propane sulfone. This reagent can be used as an eficient catalyst for the synthesis of thioamides. This new method consistently has the advantages of excellent yields and short reaction times. Further, the catalyst can be recovered for several times.

One-pot three-component reactions of aldehydes, amines, and sulfur are carried out in the presence of nano n-propylsulfonated magnetic γ-Fe2O3 as a catalyst for the synthesis of biologically interesting thioamide derivatives. The value of this catalytic method lies in its mild reaction catalyst and conditions, good yields, and ease of handling.

Small molecules with oxathiazol-2-one moiety were recently reported as potent inhibitors of Mycobacterium bovis var. bacilli Calmette-Guérin (BCG), among which HT1171 was the most potent and selective proteasome inhibitor. Herein we synthesized a series of novel compounds by bioisosteric replacement of the oxathiazol-2-one ring with 3H-1,2,4-dithiazol-3-one, and also fifteen 1,3,4-oxathiazol-2-one molecules in order for potency comparison and structure-activity relationship elucidation since their antibacterial effects on the virulent strains were not evaluated before. All the compounds were assessed for antitubercular activities on the virulent H37Rv strain by a serial dilution method. Among the tested compounds, 3H-1,2,4-dithiazol-3-one compound 4n was found to be the most active with a lowest MIC90 value of 1 μg/mL. Furthermore, the cytotoxicities of all the compounds against normal human liver cell line L02 were determined by an MTT method. Compound 4n displayed a lower inhibitory ratio than HT1171 at the concentration of 100 μM, indicating its better safety profile.

Fructose-1,6-bisphosphatase (FBPase), an important gluconeogenic enzyme, catalyzes the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate. The effort to discover new FBPase inhibitors was carried out by high-throughput screening (HTS) of a library of 56,000 lead-like compounds, and a 2,5-diphenyl-1,3,4-oxadiazole (3a, IC50 = 15.45 μM) which bearing no phosphate group was identified as a potential FBPase inhibitor for the first time. Structure-activity-relationship (SAR) research of a series of analogues obtained by modifying the substituent groups and replacing the 1,3,4-oxadiazole with several other heterocycles disclosed the key structure and substituent groups related to the binding with FBPase.
