Herein, we report a new process for the synthesis of highly functionalized pyridines based on a tandem Pummerer-type rearrangement, aza-Prins cyclization, and elimination-induced aromatization. This formal [5+1] cyclization provides pyridines in good yields with easily accessible starting materials. The synthetic potential of our new method is further demonstrated in the modification of the frameworks
在此,我们报告了一种基于串联 Pummerer 型重排、氮杂-Prins 环化和消除诱导的芳构化合成高度官能化吡啶的新工艺。这种正式的 [5+1] 环化以良好的收率提供了易于获得的起始材料的吡啶。我们新方法的合成潜力在 BINOL 和一些天然产物的框架的修改中得到了进一步证明。
