  A facile synthetic method for 2-fluoroindolizines from 1-chloro-2,2,2-trifluoroethane (HCFC-133a) and 1,1,1,2-tetrafluoroethane (HFC-134a)

  摘要：

  In the presence of KOH and Et3N. pyridinium and isoquinolinium N-ylides generated in situ from their bromides react with 1-chloro-2,2,2-trifluoroethane (HCFC-133a. bp 6 degreesC) or 1,1,1,2-tetrafluoroethane (HFC-134a, bp -27 degreesC) to give the corresponding 2-fluoroindolizines via 1,3-dipolar [3 divided by 2] cycloaddition at 80-100 degreesC in DMSO at atmospheric pressure in normal glassware.

• Synthesis of monofluorinated indolizines and their derivatives by the 1,3-dipolar reaction of N-ylides with fluorinated vinyl tosylates

  Monofluorinated indolizines 4, benzo[d]indolizines 7 and 4H-pyrrolo[1,2-a]benzimidazoles 8 were synthesized in moderate yields by 1,3-dipolar reaction between fluorinated vinyl tosylates 2a and N-ylides of pyridinium, isoquinolinium and benzimidazolinium, generated in situ from their halides salts. When the same N-ylides were allowed to react with 2,3,3-trifluoro-1-propenyl tosylate 2b, the unexpected product formylated indolizines and their derivatives 9 were obtained. The reaction mechanism is also proposed. (C) 2004 Elsevier Ltd. All rights reserved.
