Studies and Applications of Intramolecular (4+3) Cycloadditions of Pyrroles [PDF]

, 2017
While (4+3) cycloadditions commonly proceed with furans and cyclopentadienes, the corresponding reaction with pyrroles is far less reported, since pyrroles tend to undergo Friedel-Crafts type of reactions, resulting in the restoration of aromaticity ...

Formation of Bicyclic Pyrroles from the Catalytic Coupling Reaction of 2,5-disubstituted Pyrroles with Terminal Alkynes, Involving the Activation of Multiple C-H bonds [PDF]

, 2008
Substituted bicyclic pyrroles are produced directly from the coupling reaction of 2,5-disubstituted pyrroles with terminal alkynes, involving the activation of multiple C–H bonds and regioselective ...
