A simple zinc chloride mediated cyclization of ynamidyl N‐carbamates or 2‐ynamidyl‐(hetero)arylcarboxylates is achieved under mild reaction conditions, leading to the synthesis of useful heterocyclic scaffolds, 3H‐oxazol‐2‐ones and pyrrolo‐oxazin‐1‐ones, with good yields.
在温和的反应条件下,可以实现简单的氯化锌介导的氨基甲酸N-氨基甲酸酯或2-氨基氨基-(杂)芳基羧酸酯的环化反应,从而合成有用的杂环骨架,3 H-恶唑-2-酮和吡咯并恶嗪-1。收成好。
