Popis: An unprecedented allyl migration from a remote position of a quinazoline moiety through a ruthenium(II) shuttle is reported. This present cascade reaction is initiated through the formation of an η3-ruthenium–allyl complex followed by C–H allylation at the ortho position of the 2-aryl moiety. Finally, hydroamination with the quinazolinone -NH group, which is formed through tautomerization of the quinazoline, furnishes the annulation product. This exceedingly fast cascade reaction is complete within 10 minutes to provide rutaecarpine analogues in a single operation.
