    • Disclosed is a method of preparing a thiohydrazide product compound from a hydrazide starting compound. The hydrazide starting compound is represented by Structural Formula (I): The thiohydrazide product compound is represented by Structural Formula (II): In Structural Formulas (I)-(II), R1 and R2 are independently an aliphatic group, a substituted aliphatic group, an aryl group or a substituted aryl group, or R1 and R2 taken together with the carbon and nitrogen atoms to which they are bonded, form a non-aromatic heterocyclic ring optionally fused to an aromatic ring. When R2 is an aryl group or a substituted aryl group, then R5 is a hydrazine protecting group; and when R2 is an aliphatic or substituted aliphatic group, then R5 is —H or a hydrazine protecting group. R10 is —H or a substituted or unsubstituted alkyl group. The method comprising the step of reacting the starting compound with a thionylating reagent.
    • 公开了从酰肼起始化合物制备硫代酰肼产物化合物的方法。 酰肼起始化合物由结构式(I)表示:硫代酰肼产物化合物由结构式(II)表示:在结构式(I) - (II)中,R 1和R 2独立地为脂族基团,取代的脂族基团 ,芳基或取代的芳基,或者R 1和R 2与它们所键合的碳原子和氮原子一起形成任选地与芳环稠合的非芳族杂环。 当R 2为芳基或取代芳基时,R 5为肼保护基; 当R 2为脂肪族或取代的脂族基团时,R 5为-H或肼保护基。 R 10为-H或取代或未取代的烷基。 该方法包括使起始化合物与亚硫酰化试剂反应的步骤。
