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. Copyright

A method for synthesizing substituted quinolines using ruthenium-catalyzed ring-closing metathesis as a key step has been developed. Substituted 1,2-dihydroquinolines, 4-silyloxy-1,2-dihydroquinoline and 4-methoxy-1,2- dihydroquinoline, were successfully synthesized in excellent yields via ene-ene metathesis and silyl or alkyl enol ether-ene metathesis, respectively. The synthetic intermediates of the antimalarial agents quinine, chloroquine, and PPMP-quinine hybrid were efficiently synthesized by this methodology.
