Syntheses of condensed tetracyclic and pentacyclic thiazolopyrimidinones—a new class1

01 Jul 1991-Phosphorus Sulfur and Silicon and The Related Elements (Taylor & Francis Group)-Vol. 60, pp 175-181

AbstractSyntheses of tetracyclic and pentacyclic thiazolopyrimidinones (3, 6, 11 and 16) were obtained from the corresponding 2-aminothiazole derivatives (1, 4, 10 and 13) with simple methodology in fairly good yields.

Abstract: This chapter deals with new developments in the field of 1,2,3-thiadiazoles updating the second edition covering the period 1996 to 2006. Developments in structure determination, especially X-ray structures, have been reported along with new reactions of both the fully aromatic and reduced ring systems. A new method for the preparation of 1,2,3-thiadiazoles has been included as well as recent examples of the more established methods.
