Abstract

Recent work on synthetic applications of bicyclic al­kenes is reviewed, including synthesis of substituted bicyclic al­kenes, 1,3-dipolar cycloadditions, ruthenium-catalyzed [2+2] cycloadditions, ruthenium-catalyzed cyclizations and isomerizations, rhodium-catalyzed dimerizations, ruthenium- and rhodium-catalyzed ring-opening reactions.
