Ugi反应和吡啶鎓盐的[3+2]环加成反应可提供有效的多组分获得中氮茚的方法。使用氯乙酸和炔丙胺进行 Ugi 反应,然后将吡啶加成到 Ugi 加合物上,形成吡啶鎓盐。这些盐与芳基碘化物的偶联在 Sonogashira-环加成-氧化反应级联中直接产生中氮茚衍生物。
Ugi reactions and [3+2] cycloaddition of pyridinium salts have been associated to provide an efficient multicomponent access to indolizines. The pyridinium salts are formed by an Ugi reaction using chloroacetic acid and propargylamine followed by pyridine addition on the Ugi adduct. The coupling of these salts with aryl iodides gives directly indolizine derivatives in a Sonogashira-cycloaddition-oxidation reaction cascade.
