A Facile and Versatile Synthesis of Heteropolycyclic Compounds from 4-Amino-1-azabutadienes via Friedel-Crafts Cyclization of their Heterocyclic Derivatives.

Article abstract of DOI:10.1016/0040-4039(90)80105-U

Heterocyclic systems bearing an unsaturated carbon chain and aryl groups, readily accessible from 4-amino-1-azabutadienes undergo cyclization under mild acidic conditions to produce benzoisoquinolines and benzoquinazolines, as well as a new 8,13-dia
