Three ring circus: The title reaction can efficiently provide functionalized polycyclic compounds containing cyclobutene (see scheme; PG=protecting group) or aza-cyclooctene moieties in a highly regio- and diastereoselective manner with moderate to good yields under mild reaction conditions. The scope and limitations are disclosed and plausible reaction mechanisms are discussed. Copyright

Oxidative isomerization of vinylidenecyclopropanes 1 produces dimethylenecyclopropane aldehydes 2 in moderate to good yields using tetrapropylammonium perruthenate (TPAP)/4-methylmorpholine N-oxide (NMO) as a catalytic system and the obtained dimethylenecyclopropanes 3 can be transformed to indene derivatives smoothly in the presence of Bronsted acid (HOTf). The scope and limitations as well as the plausible mechanisms have been discussed.
