A concise one-pot route for the synthesis of 2,3-dihydroisoxazoles via a dual gold-iron catalysis has been devised. The method, based on the addition of binucleophilic protected hydroxylamine to propargylic alcohols, enables a one-pot, highly selective synthesis of these heterocycles (10 examples, up to 86% yield).
已经设计了通过双金-铁催化合成2,3-二氢异恶唑的简洁的一锅法。该方法基于将双亲核保护的羟胺添加到炔丙醇中,可以一锅法,高度选择性地合成这些杂环(10个实例,产率高达86%)。
