flexible approach to unknown 1-(1H-pyrrol-3-yl)pyridinium salts with selective control of the substitution patterns, by the reaction of pyridinium ylides with 2H-azirines, is disclosed. 3-(Pyridinium-1-yl)pyrrolides, a new type of stable ylide, were prepared from these salts in high yields by treatment with base. Atmospheric-pressure hydrogenation of the ylides with Adams' catalyst lead to 1-(pyrrol-3-yl)piperidines
公开了一种灵活的方法,其通过吡啶鎓吡啶化物与2 H-叠氮基的反应来选择性控制取代模式的未知的1-(1 H-吡咯-3-基)吡啶鎓盐。3-(Pyridinium-1-yl)pyrrolides,一种新型的稳定叶立德,是通过用碱处理从这些盐中高收率制备的。使用Adams的催化剂在大气压下进行氢化物氢化,可以得到高产率的1-(吡咯-3-基)哌啶。
