Abstract

A novel iron-catalyzed aminolysis of β-carbonyl 1, 3-dithianes with various amines including ammonia, primary and secondary amines, as well as hydrazine hydrate has been developed, leading to the synthesis of stereodefined β-enaminones and 3, 4-disubstituted pyrazoles in good to high yields.
