N-alkyl-pyrrole-3-carbaldehyde derivatives. The reaction involves thermal 6π-electrocyclization and aromatization of a new class of enal-azomethine ylides (EAYs). The EAYs derived from dihydroisoquinoline and 2H-azirine gave fused-pyrrole and pyridine derivatives, respectively. The synthetic importance of pyrrole products has been demonstrated by one-step synthesis of the biologically relevant pyrrolo[3,2-c]quinoline
铑催化的重氮烯醛和N-烷基亚胺的 [3 + 2] 成环反应产生N-烷基-吡咯-3-甲醛衍生物。该反应涉及一类新型烯醛-偶氮甲碱叶立德 (EAY) 的热 6π-电环化和芳构化。衍生自二氢异喹啉和2H-氮丙啶的EAY分别得到稠合吡咯和吡啶衍生物。生物相关的吡咯并[3,2- c ]喹啉支架以及片层生物碱的核心结构吡咯并[2,1- a ]异喹啉的一步合成证明了吡咯产品合成的重要性。
