Catalyst and substrate effects in enantioselective C–H insertion reactions of α-diazosulfones
… The key reaction pathways explored were C–H insertion and cyclopropanation, with hydride transfer competing in certain instances. Significantly, up to 98% ee has been achieved in the C–H insertion processes using copper-NaBARF-bisoxazoline catalysts, with the presence of the additive NaBARF …

Investigation of catalyst effects in enantioselective copper- and rhodium-mediated transformations of α-diazocarbonyl compounds
… on the use of copper-bis(oxazoline)-mediated enantioselective C–H insertion reactions leading to enantioenriched cyclopentanone derivatives. Through the use of additives, the enantioselectivity achieved with the copper catalysts for the first time reaches synthetically useful levels (up to 91% …

Synthetic and stereochemical aspects of enantioselective copper catalysed C-H insertion reactions leading to cyclopentanones and sultones
… copper–bis(oxazoline)–NaBARF catalysed C–H insertion reactions. Excellent enantioselectivities of up to 91% ee were achieved in the synthesis of cyclopentanones and up to 95% ee in the synthesis of sultones. Chapter One contains a comprehensive review providing an insight into the effect of …
