generate nylon-3 materials. Prior uses of this approach have focused almost entirely on beta-lactams with purely hydrocarbon substitutents. We show how a variety of beta-lactams bearing protected polar substituents can be generated from CSI-derived building blocks.
氯磺酰基异氰酸酯(CSI)与烯烃的反应可提供大量的β-内酰胺,并且该产品经常用于开环聚合反应以生成尼龙3材料。该方法的先前用途几乎完全集中在具有纯烃取代基的β-内酰胺上。我们展示了如何从CSI衍生的构建基元中生成各种带有受保护的极性取代基的β-内酰胺。
