Abstract
4‐Thiocarbamoyl‐5‐aminoisoxazole 4 was used as a convenient starting material for preparing both isoxazolo[5,4‐d]pyrimidine‐4(5H)thiones 5 and 4‐aminoisothiazolo[4,3‐d]isoxazole 6. The structure of the latter compound was definitively assigned by X‐ray analysis. Copyright © 1990 Journal of Heterocyclic ChemistryFile in questo prodotto:
