Rhodium catalysed chemo- and stereoselective arylative and alkenylative cyclisation reactions of unsymmetric diynes containing a terminal alkyne moiety with organoboronic acids.
Unsymmetric diynes possessing a terminal alkyne moiety reacted with organoboronic acids both chemo- and stereoselectively to afford arylated or alkenylated exocyclic dienes by catalysis from the [Rh(cod)OCH(3)](2) complex. The use of a polar protic solvent, e.g. CH(3)OH is required for the success of the process under mild conditions.
