of “TBB” to give tetrazolo(1,5-b)-isoquinolinium salts (). The latter azolium salt () showed ambidentreactivity in the presence of hydroxide ion manifested by simultaneous formation of tolualdehyde derivative and indazolo (3,2-b) isoquinoline system (). This ambidency as well as the difference in behaviour between the new linearly fused system () and its formerly studied angularly fused isomers (“annelation
