Acetolysis and thermolysis of 2-nitrosoiminothiazolidines

Abstract

2-Nitrosoiminothiazolidine (1) with acetic anhydride and pyridine gives thiazolidin-2-one, 3-acetylthiazolidin-2-one and 2-thiocyanatoethyl acetate. Thermal decomposition of (1) and of its 3-methylderivative (2) forms thiazolidin-2-ones.
