Phosphorus Sulfur and Silicon and The Related Elements | 1988

THE CHEMISTRY OF 3-AMINOTHIOACRYLAMIDES; PART II: 3-AMINOTHIOACRYLAMIDES AS USEFUL SYNTHONS IN ORGANIC SYNTHESIS

Jürgen Liebscher; Berhanu M. Abegaz; Alexander Knoll

Abstract 3-Aminothioacrylamides are a class of organic sulfur containing compounds that are easily available and exhibit polyfunctional reaction behaviour. They can be used widely in the synthesis of a variety of heterocyclic and open chain compounds. The synthetic utility of 3-aminothioacrylamides can be further extended if additional functionalities are incorporated.
