A simple and convenient copper-catalyzed intermolecular cyclization reaction for the synthesis of quinolines from anilines and terminal acetylene esters has been developed. This methodology constructs the C–N and C–C bonds successively via a cascade process, and provides the desired products in moderate to good yields.
The scope and limitations of the ruthenium-catalyzedpropargylic substitution reaction of propargylicalcohols with heteroatom-centered nucleophiles are presented. Oxygen-, nitrogen-, and phosphorus-centered nucleophiles such as alcohols, amines, amides, and phosphine oxide are available for this catalytic reaction. Only the thiolate-bridged diruthenium complexes can work as catalysts for this reaction
