An overview on the applications of ‘Doyle catalysts’ in asymmetric cyclopropanation, cyclopropenation and C–H insertion reactions

The chiral dirhodium(II) carboxamidates are a unique class of chiral catalysts useful for asymmetric inter- and intramolecular cyclopropanation, cyclopropenation and C–H insertion reactions with excellent enantioselectivities. The broad applications of these catalysts in organic syntheses are briefly reviewed.
