A Cu-catalyzed [3+2]-type condensation reaction of oxime acetates and dialkyl acetylenedicarboxylates that provides highly substituted pyrroles under aerobic conditions is described. The newly formed pyrroles are easily employed for further transformations to prepare pyrrolo[2,1-a]isoquinoline skeletons. The Royal Society of Chemistry 2013.

O-Vinyl oximes were synthesised from the reaction of oximes with activated alkynes and subsequently rearranged using gold catalysis to afford highly substituted pyrroles in an efficient and regiocontrolled process. Additionally, pyrroles were formed direc
Reactions of a 2H-Azirine with Electron-rich Olefins; Synthesis of Dimethyl Pyrrole-2,3-dicarboxylates

The electron-deficient 2H-azirine (2) reacts with enamines and α-oxo phosphorus ylides to give the pyrrole-2,3-dicarboxylates (3)-(6); α-ester phosphorus ylides, on the contrary, furnish the substituted vinyliminophosphoranes (7) and (8).
