A new approach to construct 2,3-disubstituted quinolines is described via Pd-catalyzed oxidative cyclization of o-vinylanilines and alkynes with molecular oxygen. This transformation is supposed to undergo intermolecular amination of alkyne, insertion of the olefin, and oxidative cleavage of C–C bond sequence.

to polyfunctionalized quinolines was developed. In the presence of a highly efficient combination encompassing (PPh)3AuCl and AgOTf, the reactions between 2-aminocarbonyls and an array of internal alkynes proceeded smoothly to afford quinoline derivatives in good to excellent yields (up to 93%).

first heterogeneous intermolecular cycloaddition of 2-aminoaryl carbonyls and internal alkynes was realized in DMF at 100 °C by using a triphenylphosphine-functionalized MCM-41-supported gold(I) complex [MCM-41-PPh3-AuCl] and AgOTf as catalysts, yielding a variety of polyfunctionalized quinolines in good to excellent yields. This heterogeneous gold(I) complex could easily be prepared via a simple two-step

diversely substituted quinoline and quinolin-2-one derivatives is disclosed. In situ generated nickel boride proved to be an effective promoter of the reductive cyclization reaction. Broad substrate scope, mild reaction conditions, consistent yield, and a wide range of functional group tolerance are the other notable features of the newly discovered reaction. A large number of quinoline and quinolin-2-one
