Asymmetric synthesis in carbon–carbon bond forming reactions of α-diazoketones catalysed by homochiral rhodium(<scp>II</scp>) carboxylates

Abstract

Partial asymmetric synthesis has been observed in intramolecular C–H insertion, aromatic cycloaddition, and cyclopropanation reactions of α-diazoketones catalysed by homochiral rhodium(II) mandelate and rhodium(II) carboxylates derived from L-proline.
