Abstract

Abstract 4-Amino-1, 2, 5-selenadiazole-3-carboxylic acid and 4-amino-1, 2, 5-selenadiazole- 3-carboxamides have been prepared by ring-cleavage of [1, 2, 5] selenadiazolo [3, 4-d] pyrimidin-7 (6H)-one by basic reagents. The primary amide (III), as well as an N-alkyl amide, may be produced by the action of a primary amine. Hydrazine reductively cleaves the selenadiazole ring. The preparation of similar 4-ureido derivatives by ring-cleavage of [1, ...
