The one‐pot tandem reaction of N‐alkyl‐N‐allyl‐2‐vinylaniline derivatives with benzo‐ or naphthoquinones and a ruthenium–alkylidene catalyst leads to isoindolo[2,1‐a]quinolines in a variety of colors, which can be altered by exchanging the substituent on the core heterocycle (see scheme). This reaction offers a new synthetic method for π‐conjugated small molecules from simple aniline derivatives.
