Abstract
Abstract A series of diverse polyfunctionalized quinolines were easily prepared in excellent yields via a Friedlander reaction of o-aminoaryl ketone or o-aminoaryl aldehyde with α- methylene ketones using lithium triflate as an expeditious catalyst under solvent free conditions. The protocol provides a practical and straightforward approach toward highly functionalized quinoline derivatives in excellent yields. The catalyst is easily recoverable ...
