Oxabicyclo[2.2.1]norbornenes constitute a convenient and readily cleaved linker for solid-phase organic synthesis. A simple and inexpensive furfuryl-substituted resin has been shown to capture and release maleimide dienophiles under conditions compatible with intermediate synthetic steps. The synthesis of β-amino, -thiophenoxy, and -hydrazino alcohols by epoxide ring opening, and maleimide-functionalized
氧杂双环[2.2.1]降冰片烯构成用于固相有机合成的方便且容易裂解的连接基。已经显示出一种简单且廉价的糠基取代的树脂可以在与中间合成步骤兼容的条件下捕获并释放马来酰亚胺二烯。描述了通过环氧化物开环合成β-氨基,-硫代苯氧基和-肼基醇,以及通过标准肽偶联技术合成马来酰亚胺官能化的亮-脑啡肽,以说明固相合成方法的实用性。
