The electrophilic substitutions of di and tri substituted imidazo[2,1-b]oxazoles were studied. Mannich, bromination, nitration, and the Vilsmeier-Haack formylation reactions occur at position-5 of this ring system to give a range of products in high yield.
研究了二和三取代的咪唑并[2,1- b ]恶唑的亲电取代。曼尼希(Mannich),溴化,硝化和Vilsmeier-Haack甲酰化反应发生在该环系统的5位,从而提供了一系列高收率的产品。
