The synthesis of the biologically active alkaloid simulenoline, isolated from the roots of Zanthoxylum simulans, is reported. The natural product was assembled from simple commercial reagents via initial domino Knoevenagel/oxa-6π-electrocyclization followed by a one-pot singlet-oxygen ene-reaction/reduction sequence. New insights of singlet oxygen reactivity with olefinic substrates have been revealed
报道了从花椒模拟物的根中分离出的具有生物活性的生物碱simulenoline的合成。天然产物是由简单的商业试剂通过最初的多米诺(Domino)Knoevenagel /oxa-6π-电环化,然后是一锅单线态氧烯反应/还原序列组装而成的。已经揭示了单线态氧与烯烃底物的反应性的新见解。
