Cs2CO3-promoted [3 + 3] annulations under mild reaction conditions enabled facile decoration of a number of functional groups at the pyridine moiety by way of a domino N-alkylation-intramolecular aldol condensation procedure to afford a wide range of novel indolizines such as 8-acylindolizines, 8-enylindolizines, and coumarin-indolizine hybrids. 2025-07-01T00:00:00Z
