Reaction Mechanism[edit]
It seems to me that the reaction mechanism described in the article would lead to the wrong isomer of the pyrrole products. Dragonix8 (talk) 03:02, 7 October 2022 (UTC)
The reaction mechanism is right. But the first scheme is wrong. R3 and R4 should be inverted on the pyrrole. The R4 group must be on the alpha of the nitrogen (N) (on its left). — Preceding unsigned comment added by 139.124.188.89 (talk) 14:02, 11 January 2023 (UTC)
