addition of 1H-indole/pyrrole-2-carboxylic acids with Morita–Baylis–Hillman-derived allylamines. The readily available starting materials, good stereoselectivity, and gram-scale synthesis make this method valuable for the construction of highly substituted fused heterocycles containing the 1,4-diazepanone moiety.
已经开发出一种用于吲哚/吡咯融合的1,4-二氮杂潘酮支架的一锅法合成方法。此方法涉及将1 H-吲哚/吡咯-2-羧酸与森田-贝利斯-希尔曼衍生的烯丙胺依次进行酰胺偶联/分子内氮杂-迈克尔加成反应。容易获得的起始原料,良好的立体选择性和克级合成方法使该方法对于构建含有1,4-二氮杂酮部分的高度取代的稠合杂环具有重要意义。
