We report, herein, a palladium-catalyzed cascade comprising carbopalladation, migratory insertion of isocyanide and triple bond activation followed by a nucleophilic attack (OR?) to construct difunctionalized acyl indoles. The process involves

A new synthetic approach for the synthesis of indolo[2,3-b]quinolines and benzothieno[2,3-b]quinolines has been developed by employing the freshly prepared o-alkynylisocyanobenzenes derived from o-alkynylformamide derivatives as substrates. The synthetic transformations involved chloride-ion-triggered 6-endo cyclization of o-alkynylisocyanobenzenes to generate 2-chloroquinolines in situ, which further cyclized intramolecularly with nitrogen or sulfur atom via a cascade process to provide the corresponding indolo[2,3-b]quinolines and benzothieno[2,3-b]quinolines, respectively, in moderate to excellent yields.

A facile synthesis of various functionalized 3-substituted quinolin-2(1H)-ones through Ag(i) nitrate-catalyzed cyclization of o-alkynylisocyanobenzenes is described. The reaction allows rapid and convenient access to 3-substituted quinolin-2(1H)-one scaffolds in moderate to good yields.
