Abstract
In search of new antimycotic agents acting as ergosterol biosynthesis inhibitors we investigated widely new and optimized reaction pathways for preparing different types of triazasteroids [1, 2]. The various mono-, bi-, tri- and tetracyclic triazasteroidal compounds are designed as stable aza-analogues of carbo-cationic high energy intermediates (HEIA) of fungal enzymes [1, 2].
