A Bronsted acid, trifluoromethanesulfonimide [HN(SO2CF3)2], was found to catalyze reductive β-alkylation of pyrroles with carbonyl compounds and hydrosilanes. This metal-free process features lower catalyst loadings compared to the original indium variant and exclusive generation of β-alkylpyrroles.

Reactions of 2-chlorocyclopropanecarboxaldehydes with primary amines in boiling DMF lead in good yield to 1-substituted pyrroles. 2-Chlorocyclopropanecarboxaldehydes were synthesized by the stereoselective reduction of the corresponding 2,2-dichlorocyclopropanemethanols with lithium tetrahydroaluminate with the subsequent oxidation of the mixture of stereoisomeric 2-chlorocyclopropanemethanols with pyridinium chlorochromate.
