Ruthenium‐Catalyzed Hydroamination of Aminoallenes: an Approach to Vinyl Substituted Heterocycles

Abstract

Abstract Heterosubstituted aminoallenes underwent smooth ruthenium‐catalyzed intramolecular exo ‐hydroamination reactions yielding the corresponding five‐, six‐, or seven‐membered 1,3‐diaza‐ or 1,3‐oxaza‐heterocyclic structures. This procedure is a valuable and less expensive alternative to the already known transition metal‐catalyzed hydroamination reactions of aminoallenes. magnified image
