A simple and efficient one-pot synthesis of N-substituted-1,2-dihydropyridines, indenopyridines and 5,6-dihydroisoquinolines by a BF3·Et2O mediated novel methodology, from easily available α,β-unsaturated ketones/arylidene ketones, phenyl acetylenes and substituted nitriles, has been described. This novel annulation provides quick access to complex polycyclic frameworks with an excellent substrate
由BF 3 ·Et 2 O介导的新颖方法,由易于获得的α,β-不饱和酮/亚芳基酮简单有效地一锅合成N-取代的1,2-二氢吡啶,茚并吡啶和5,6-二氢异喹啉已经描述了苯基乙炔和取代的腈。这种新颖的环形结构可快速访问复杂的多环骨架,并具有出色的底物范围。
