G. Cirrincione et al., NUCLEOPHILIC REACTIONS IN THE PYRROLE SERIES - DISPLACEMENT OF HALOGEN AS A TOOL TO FUNCTIONALIZE THE PYRROLE NUCLEUS, Synthesis, (10), 1997, pp. 1169
Nucleophilic substitutions on halopyrroles by charged and neutral carb
on, nitrogen, oxygen and sulfur nucleophiles are reported. Such reacti
ons represent a valuable and versatile instrument to prepare a wide va
riety of functionalized pyrroles and to obtain building blocks for the
synthesis of polycyclic systems.
