transformation of indoles with 2-nitrostyrenes was developed, allowing for the one-pot assembly of heterocyclic scaffolds with four fused rings. This strategy was subsequently employed for the concise total synthesis of two natural products, the alkaloids norneocryptolepine and neocryptolepine.
开发了一种创新的酸辅助吲哚与 2-硝基苯乙烯级联转化,允许一锅组装具有四个稠环的杂环支架。该策略随后被用于两种天然产物,生物碱去甲隐碱和新隐碱的简明全合成。
