yet highly effective approach toward enantioselective synthesis of trans-3,4-disubstituted glutarimides from readily available starting materials is developed using oxidative N-heterocyclic carbene catalysis. The catalytic reaction involves a formal [3 + 3] annulation between enals and substituted malonamides enabling the production of glutarimide derivatives in a single chemical operation via concomitant
利用氧化的N-杂环卡宾催化,开发了一种简单而高效的方法,可从容易获得的起始原料中进行对映选择性合成反式3,4-二取代的戊二酰亚胺。催化反应包括在烯醛和取代的丙二酰胺之间进行正式的[3 + 3]环化反应,从而可以通过同时形成C–C和C–N键在单个化学操作中生成戊二酰亚胺衍生物。该反应可轻松获得具有出色的对映选择性和良好收率的多种功能化戊二酰亚胺。通过(-)-帕罗西汀和其他生物活性分子的正式合成证明了该方法的合成应用。
