A new method for the synthesis of 2- and 3-substituted indolylalkylamides, derivatives of melatonin, from arylhydrazines and amidoketones by the Fischer reaction was elaborated. The amidoketones can be easily prepared from cyclic imines by reaction with acylpyridinium chloride. This method is a one-step synchronous creation of the selected alkylamide fragment and the indole core. Variation of the arylhydrazines
阐述了一种通过费歇尔反应从芳基肼和酰胺酮合成褪黑激素衍生物的2-和3-取代的吲哚基烷基酰胺的新方法。通过与酰化吡啶鎓氯化物反应,可以容易地由环状亚胺制备酰胺酮。该方法是一步一步同步创建所选的烷基酰胺片段和吲哚核。的芳基肼的变化创造indolylalkylamides和酰胺酮的合适的选择可以直接酰胺烷基链的吲哚的2位或3位的碳环所需的取代基。
