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.
通过氧代环己烯基异噁唑啉酮缩合物及其二聚体形成了一种仿真azasteroid或azasteroid的中间体,可用于制备azasteroid和azasteroid仿真物。该二聚体可用于形成一元和二元肼酮,可作为azasteroid仿真物或azasteroid的制备中间体。通过肼化和可选的脱肼化进行该二聚体和azasteroid仿真物或azasteroid的制备中间体的制备方法。将氮原子插入到二聚体的六元环中的C-17位环己烯酮基团中,从而产生还原的四氮杂[1,5-a]环庚烯-8-基团。在苄基酮处进行随后的氢酮形成,可生成具有(triazol-4-yl)imino取代基的azasteroid仿真物。一元肼酮可转化为它们的硫醚等效物。
