ABSTRACT This brief review describe the recent advances in using oxamic acid thiohydrazides as precursors for the formation of hydrazones intermediates from natural and synthetic compounds bearing a carbonyl group. These intermediates undergo a variety of synthetically useful transformations, which include nucleophilic addition and 6π-electrocyclic reactions to generate new heterocycles.
