We formerly developed a convenient general method of monothiooxamides synthesis by reaction of available chloroacetamides with a preliminary prepared solution of elemental sulfur in amines [1]. Synthetic approaches basing on modifications of amide and thioamide groups in the monothiooxamides are promising for building up a wide range of various compounds. For instance, we showed that modification of the thioamide group in the monothio- oxamides effected with ...
