title: Synthesis and fluorescent properties of the tricyclic analogues of acyclovir linked with nitrogen hetbrocyclic units.
abstract: Tricyclic (T, 3,9-dihydro-9-oxo-SH-imidazo[g2-c]purine) analogues of acyclovir (ACV, 1), substituted in the 6 position with pyrid-4-yl, 4-(pyrid-4'-yl)Ph, 4-(pyrimidin-5-yl)Ph and 4-(thiazol-2'-yl)Ph units were synthesized. For the synthesis of the heteroarylphenyl derivatives, a convenient general route was developed, ie., Suzuki cross-coupling between protected 6-(4-dihydroxyborylphenyl) TACV and easily available bromoheterocycles. Fluorescent properties of newly synthesized TACV aoalogues strongly depend on the nature of a solvent. This sensitivity of fluorescence makes the compounds promising probes of H-bonding in the environment.
