The synthesis of 8-aminoquinolines and 1,10-phenanthrolines with substituents in α of the nitrogen has been performed through an inverse-demanding aza-Diels–Alder (Povarov reaction) in the fluoroalcohols TFE or HFIP. This path involves simple starting materials: 1,2-phenylenediamines, enol ethers and aldehydes.
在氟醇类溶剂(TFE或HFIP)中,通过逆电子需求的氮杂狄尔斯-阿尔德反应(Povarov反应),实现了在氮原子α位带有取代基的8-氨基喹啉和1,10-菲咯啉的合成。这条路径使用简单的起始原料:1,2-苯二胺、烯醚和醛类。
