The reaction of sodium cyanate with benzo[b]quinolizinium substrates at room temperature gave 3-hydroxy-4-pyridyl-isoquinoline derivatives in good yields. Presumably, the overall reaction proceeds through an ANRORC-type sequence, that is, addition of the nucleophile, ring opening, and ring closure. Preliminary photophysical investigation of the parent compound revealed a pronounced sensitivity of its
