Two series of 3-mercapto-1,2,4-triazole derivatives containing alkoxy substituents different in size and position were synthesized and their structures were characterized by FT-IR, 1H NMR, 13C NMR spectroscopy and elemental analysis. The synthesized compounds were assessed for their antiproliferative activity against colon cancer cell line (SW480). The results indicated that the size and position of the alkoxy group significantly influenced the antiproliferative activity. The highest cancer cell growth inhibition values were observed for the compounds containing 3,4,5-trimethoxyphenyl groups in their structures (57.74, 54.14 and 60.70% at 50 μM for compounds 5a, 12b and 14, respectively). The synthesized compounds were also subjected to DPPH protocol for evaluating the antioxidant activity. The results showed that all compounds had moderate to high levels of antioxidant capacity as compared to ascorbic acid as standard, the highest free radical scavenging capacity of 75% was observed for compound 4a at 50 μM.

Here, we report O-methyl S-aryl thiocarbonates as a versatile esterification reagent for palladium-catalyzed methoxycarbonylation of arylboronic acid in the presence of copper(I) thiophene-2-carboxylate (CuTC). The reaction condition is mild, and a variety of substituents including sensitive-Cl,-Br, and free-NH2 could be tolerated. Further applications in the late-stage esterification of some pharmaceutical drugs demonstrate the broad utility of this method.

The synthesis of methyl esters has been carried out via the reaction of aliphatic and aromatic carboxylic acids with dimethyl carbonate in the presence of manganese and iron carbonyls. The optimal ratio of catalyst and reagents and other conditions for the synthesis of methyl esters of carboxylic acids with high yield have been found.
