Octa-5,7-dienylidenecyclopropanes undergo [4 + 3] intramolecularcycloaddition reactions upon treatment with appropriate palladium catalysts to give stereochemically rich bicyclo[5.3.0]octane systems in a completely diastereoselective manner.

The ring-closingreactions based on chemical bond metathesis enable the efficient construction of a wide variety of cyclic systems which receive broad interest from medicinal and organic communities. However, the analogous reaction with C-N bond metathesis as a strategic fundamental step remains an unanswered challenge. Herein, we report the design of a new fundamental metallic C-N bond metathesis reaction
