Use of metal complexes of chiral nonracemic ligands in asymmetric cyclopropanation reactions via homogeneous catalysis is one of the recent developments in synthetic organic chemistry. The extra carbon in the cyclopropane unit from the cyclopropanation of olefins comes from diazo esters or dihalomethanes. In this article we shall discuss the recent aspects of asymmetric intermolecular cyclopropanation reactions where decomposition of these compounds to carbenoid species takes place by organometallic complexes.
