A gold-catalyzed sequential reaction of O-allyl hydroxamates bearing an alkyne moiety has been developed for the preparation of 3-hydroxyisoxazoles and isoxazole-3-ones. Notably, this domino reaction involving cyclization and rearrangement provided facile access to the desired compounds in a highly atom-economical manner.
已经开发了具有炔基部分的O-烯丙基异羟肟酸酯的金催化的顺序反应,用于制备3-羟基异恶唑和异恶唑-3-酮。值得注意的是,该涉及环化和重排的多米诺反应提供了以高度原子经济的方式容易地获得所需化合物的方法。
