手性非外消旋配体金属络合物在均相催化不对称环丙烷化反应中的应用是合成有机化学的最新进展之一。环丙烷单元中来自烯烃环丙烷化的额外碳来自重氮酸酯或二卤代甲烷。在这篇文章中,我们将讨论不对称分子间环丙烷化反应的最新进展,在这些反应中,有机金属配合物将这些化合物分解为类卡宾物种。
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.
