Fang, Xiang published the artcileSynthesis of monofluorinated indolizines and their derivatives by the 1,3-dipolar reaction of N-ylides with fluorinated vinyl tosylates, COA of Formula: C7H7ClN2, the publication is Tetrahedron (2004), 60(25), 5487-5493, database is CAplus.
Monofluorinated indolizines, benzo[d]indolizines and 4H-pyrrolo[1,2-a]benzimidazoles were synthesized in moderate yields by 1,3-dipolar cycloaddition reaction between fluorinated vinyl tosylates and N-ylides of pyridinium, isoquinolinium and benzimidazolium, generated in situ from their halide salts. When the same N-ylides were allowed to react with 2,3,3-trifluoro-1-propenyl tosylate, the unexpected product formylated indolizines and their derivatives, e.g., I, were obtained. A reaction mechanism is also proposed.
