rearrangement of 2-propargyloxypyridine and 2-(but-3-yn-1-yloxy)pyridine under acidic conditions. This approach exhibits significant utility due to its outstanding efficiency of conversion in the synthesis of secondary amines as a one-pot reaction. The initial step of the method involves a cyclization reaction for the production of pyridinium salts, followed by the next stage, where rearrangement is
通过在酸性条件下
金催化的 2-炔丙氧基
吡啶和 2-(but-3-yn-1-yloxy)pyridine 重排,可以高产率得到N-烯基 2-
吡啶酮胺。由于在一锅反应合成仲胺中具有出色的转化效率,因此该方法具有显着的实用性。该方法的第一步涉及环化反应以产生
吡啶鎓盐,然后是下一阶段,其中通过亲核加成现象完成重排。这种方法将
伯胺转化为仲胺,从而产生单一产品。此外,该方法对几种
