A general procedure for the synthesis of azabicyclic ring systems viz. indolizidine, pyrrolizidine and quinolizidine has been developed utilizing proline-catalyzed sequential α-amination and Horner–Wadsworth–Emmons (HWE) olefination of an aldehyde as the key step. This method can be further extended to the synthesis of various biologically active natural products containing azabicyclic ring systems
合成氮杂双环系统的一般程序。 吲哚嗪, 吡咯嗪 和 喹oli嗪利用脯氨酸催化的连续α-胺化和醛的Horner-Wadsworth-Emmons(HWE)烯化反应作为关键步骤,已开发出了该化合物。该方法可以进一步扩展到合成各种含有氮杂双环系统的生物活性天然产物。
