1-Vinylpyrroles are formylated by the N-N dimethyl- formamide/oxalyl chloride reagent system (CH2Cl2, r.t., 40 min) to give the corresponding 1-vinylpyrrole-2-carbaldehydes in yields up to 97%. Georg imeme Verlag Stuttgart.

1-Vinylpyrrole-2-carbaldehydes and 1-vinyl-4,5-dihydrobenzo[g]indole-2-carbaldehyde were synthesized in 56-91% yields from their 1-vinyl derivatives by a modified Vilsmeier-Haack reaction. A low temperature (-78 °C) is required to avoid removal of the N-v
