the corresponding bis-thiolated indolederivatives. The advantages of the reaction include metal-free, room-temperature, mild reaction conditions and broad functional group compatibility. The reaction proceeds via nucleophilic addition of an alkanethiol to an isonitrile moiety, 5-exo cyclization, followed by nucleophilic addition of an alkanethiol to a 3-alkylidene indole intermediate.

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.

We report, herein, a palladium-catalyzed cascade comprising carbopalladation, migratoryinsertion of isocyanide and triple bond activation followed by a nucleophilic attack (OR−) to construct difunctionalized acyl indoles. The process involves multiple bond formations via key palladium-chemistry steps, to construct these bis-heterocycles containing two privileged scaffolds (indole and oxindole) in
