A facile synthesis of benzofuro[2,3‐c]pyridines has been achieved under mild conditions by using ammonium acetate as the nitrogen source through intramolecular cascade annulation. This reaction could efficiently construct pyridinering and furanring in one step. Moreover, the key annulation step was demonstrated through dihydrobenzofuran intermediates.
在轻度条件下,通过乙酸铵作为分子内级联环氧化氮源,可以轻松合成苯并呋喃[2,3- c ]吡啶。该反应可一步有效地构建吡啶环和呋喃环。此外,关键的环合步骤通过二氢苯并呋喃中间体进行了证明。
