Abstract

Metal-catalyzed intermolecular cycloaddition reactions are powerful tools for the construction of complex carbo-and heterocyclic frameworks.[1, 2] The development of new allcarbon building units is a key focus in this area. Five-and sixmembered carbo-and heterocycles are readily accessed by metal-catalyzed [3C+ 2],[4C+ 2], and [3C+ 3] cycloaddition reactions,[1, 2] but less commonly through a [4C+ 1] or [5C+ 1] cycloaddition ...
