SYNTHESIS OF ISOQUINOQUINAZOLINES BY CYCLOADDITION REACTION
Kanmacher, Isabelle,Stambach, Jean-Francois,Jung, Louis
, p. 2131 - 2138 (2007/10/02)
The cycloaddition reaction of 3,4-dihydroisoquinolinium salts (2c,d) with 2-aminobenzaldehydes (1a,b) was a convenient way to obtain 5,6,13,13a-tetrahydro-8H-isoquinoquinazolinium salts (3a-d).The reduction, transposition and oxidation of these com
