Abstract:
An azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic is formed via an oxocycloalkenyl isoxazolium anhydrobase and its dimer. The dimer can be used to form mono- and dihydrazones, which can be an azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic. A method of preparation of the dimer and the azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic occurs with hydrazonation and, optionally, a subsequent dehydrazonation. The dimer can be converted by inserting a nitrogen atom into the six membered ring of to a C-17 position cyclohexenone moiety of the dimer to yield a reduced tetrazolo[1,5-a]azepin-8-yl group. A subsequent hydrozone formation at a benzylic ketone can be carried out to generate an azasteroid mimic with a (triazol-4-yl)imino substituent. Monohydrazones can be converted to their thione equivalents.
