Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds.
Alkene cross-metathesis was efficiently used as a means of chain elongation in the recent enantioselective synthesis of the revised structure of azaspiracid-1. Functionalized and higher olefins from simple alkene precursors cross metathesis has recently gained prominence due to selectivity in olefin cross metathesis.
