The synthesis of naphthalene derivatives through three-component coupling of 2-alkynylbenzaldehyde hydrazones with carbene complexes and electron-deficient alkynes has been examined. The reaction involves formation of an isoindole derivative, followed by intramolecular Diels-Alder reaction, followed by nitrene extrusion. The reaction was highly regioselective using unsymmetrical alkynes.
已经研究了通过 2-炔基苯甲醛腙与卡宾配合物和缺电子炔烃的三组分偶联合成萘衍生物。该反应包括形成异吲哚衍生物,然后是分子内 Diels-Alder 反应,然后是氮烯挤出。该反应使用不对称炔烃具有高度区域选择性。
