已开发出一种微波辅助的氟合成路线,用于 3-氨基-1,2-苯并恶唑和4-氨基-1 H -2,3-苯并恶嗪。该策略包括将各自的2-氟苄腈或2-(溴甲基)苄腈与氟肟标签连接,得到芳基肟中间体,然后将其进行环化,同时在酸性条件下将底物标签裂解,从而提供所需的产物,中等至中等产量。另外,可以使芳基肟中间体进一步反应以扩展化合物库。可以使用氟固相萃取(F-SPE)轻松分离产物,回收的氟酮可以转化回氟肟,并在下一轮合成中重复使用。

Herein, we report a nickel-catalyzed intramolecular denitrogenative dual annulation reaction of aryl nitrile-containing 1,2,3-benzotriazine-4(3H)-ones to synthesize polycyclic pyrroloquinazolinones with a tolerance of a wide diversity of substituents. This catalytic reaction is the first denitrogenative transannulation of 1,2,3-benzotriazine-4(3H)-one with nitrile, which can be applied as the critical
在此,我们报道了含芳基腈的1,2,3-苯并三嗪-4(3 H )-酮的镍催化分子内脱氮双环化反应,合成了具有多种取代基的多环吡咯并喹唑啉酮。该催化反应是1,2,3-苯并三嗪-4(3H)-酮与腈的首次脱氮转环反应,可作为合成洛托宁A的关键步骤,具有较高的步骤经济性。
