Abstract Palladium‐catalyzed (3+3) and (3+4) cycloannulations between vinylcyclopropanes various (hetero)aromatic aldehydes are reported. The use of phosphonate‐substituted provides access to a variety bi‐ or tricyclic heteroaromatic scaffolds via an allylation/olefination cascade. nature the mechanism was investigated by control experiments. magnified image
