Resum:
This journal is © The Royal Society of Chemistry. The successful rhodium catalysed asymmetric intermolecular hydroaminomethylation (HAM) of alkenes using a single catalyst bearing the (R,R)-QuinoxP∗ ligand is reported. The HAM of α-alkyl acrylates is revealed to be an efficient tool for the regio- and enantioselective synthesis of γ-amino esters with ees up to 86%. HPNMR experiments provided insights into the reaction mechanism.
