Summary Eight new tetracyclic fused as-triazines (4–6,8,11–13, and15) have been synthesized by conversion and subsequent ring transformation of 1,2-diaminoisoquinolinium (2) and -quinolinium salts (9) with 4-benzoyl-5-phenylfuran-2,3-dione (1). Selective alkylations of the new products revealed that these reactions are governed mainly by the electronic density of the lone pairs as well as by steric effects.Dedicated to em. Univ.
