Synthesis of benzo(or furo)[5,6]azepino[2,1-a]isoindolone derivatives: π-cyclisations of N-acyliminium ions
摘要:
Benzo(or furo)[5,6]azepino[2,1-a]isoindolone and derivatives were obtained easily in one-pot via N-acyliminium ions by treatment of 2-(2-methoxycarbonylbenzyl(or fur-3-yl))phthalimide with alkylmagnesium iodide followed by an acidic hydrolysis. (C) 1998 Elsevier Science Ltd. All rights reserved.

isoindolo[1,3]benzo(or thieno)oxazepines 8a,b and one of their positional isomers aromatic tricyclic N,O-acetals 13b are reported to occur efficiently in a three-step sequence from N-hydroxy-methylphthalimide (6). The key step of this methodology is the intramolecular arylation of an endocyclic and/or exocyclic N-acyliminium cation. The mechanism leading to these species, in particular to a tricyclic lactam
