THE CHEMO- AND REGIOSELECTIVITY OF THE CYCLIZATION OF THIOSEMICARBAZIDES WITH HALOACETIC ACIDS AND THEIR DERIVATIVES

Abstract
The effect of the structural features of the starting thiosemicarbazides as well as the cyclization reaction conditions on the chemo- and regioselectivity of the formation of heterocyclic systems is discussed.
