Indolizine is an aromatic 1 On-electron system and constitutional isomer of l-H indole and, consequently, has received a considerable theoretical and practical interest [100]. Considering the well-established fluorescence properties of indolizines [101-103] and biindolizines [102], and the steadily increasing importance of fluorophores in biolabeling and environmental trace analysis, we have been seeking for a new, efficient synthesis of fluorescent indolizines. Two general ways of indolizine syntheses have been known so far [100]. The first route is based on the intramolecular formation of the indolizine by cyclocondensation of suitable pyridinium precursors. However, the second approach takes advantage of a [3 + 2]...
