3-Thiadiazolylureas containing aminoacid residues were synthesized. These compounds were converted to 5-sulfanyl-1,2,3-triazol-1-ylaminocarboxylic acid sodium salts under alkaline conditions. These salts were found to inhibit the oxidation of ascorbic acid with air oxygen. In the presence of the equimolar amount of 5-sulfanyl-1,2,3-triazoles, the rate of diminution of ascorbic acid decreased by 1.5—3 times
Selenium heterocycles XVIII: Synthesis and antibacterial activity of 4‐substituted (1,2,3‐selenadiazol‐5‐yl)carbamic acid esters and their sulfur analogs
4-Substituted (1,2,3-selenadiazol-5-yl)carbamicacidesters and their sulfuranalogs were prepared from the Curtius rearrangement of the corresponding carboxazides. None of the compounds showed significant antibacterialactivity.

Novel unknown potentially biologically active 1-(1,2,3-thiadizolylcarbonyl)-4-(1,2,3-thiadiazolyl)-semicarbazides were synthesized by reactions of 1,2,3-thiadiazolylcarboxylic acid hydrazides with 1,2,3- thiadizolylcarbonyl azide in high yields. The structure of the synthesized compounds was studied by NMR and IR spectroscopy and X-ray diffraction analysis.
