Oxidation of 2-furylaninlies with m-CPBA followed by treatment with a base provides access to functionalized indolin-3-ones. The designed oxidative transformation utilizes an underassessed chemical behavior of furyl-containing amines to form a C–N bond via engaging a β-carbon atom of the furan core upon a ring-forming step, thereby providing an alternative disconnection toward nitrogen-containing heterocycles
用m -CPBA 氧化 2-呋喃丙氨酸,然后用碱处理,可得到功能化的吲哚啉-3-酮。设计的氧化转化利用了含呋喃基胺的一种未被充分评估的化学行为,通过在成环步骤中与呋喃核心的β-碳原子接合来形成C-N键,从而提供了一种与含氮杂环断开的替代方法。
