This review summarizes diverse synthetic protocols for the preparation of pyrrolo[2,1-][1,2,4]triazine derivatives, covering literature sources from the past two decades. For effective representation, the synthetic methods toward the title compound are classified into six distinct categories: 1) synthesis from pyrrole derivatives, 2) synthesis bromohydrazone, 3) synthesis formation of triazinium dicyanomethylide, 4) multistep synthesis, 5) transition metal mediated synthesis, and 6) rearrangement of pyrrolooxadiazines. A brief outline of all optimized schemes is provided with relevant examples.
本综述总结了过去二十年来文献中用于制备吡咯并[2,1-][1,2,4]三嗪衍生物的各种合成方法。为了便于有效呈现,合成该标题化合物的方法分为六个不同类别:1)由吡咯衍生物合成;2)由溴腙合成;3)由三嗪二氰甲基化物形成合成;4)多步合成;5)过渡金属介导的合成;6)吡咯并恶二嗪的重排。文中提供了所有优化方案的简要概述及相关示例。
