title: Convergent, regiospecific synthesis of quinolines from o-aminophenylboronates.
abstract: A direct convergent two-component synthesis of quinolines from alpha,beta-unsaturated ketones and o-aminophenylboronic acid derivatives is reported. The reaction is regiocomplementary to the traditional Skraup-Doebner-Von Miller synthesis and proceeds under basic rather than strongly acidic conditions. Quinolines substituted in the benzenoid ring can be accessed by using substituted o-aminophenylboronates prepared by direct palladium-catalyzed borylation of the corresponding o-bromoanilines.
