First intramolecular enantioselective iridium-catalysed allylic aminations.
Enantioselective iridium-catalysed intramolecular allylic aminations, using phosphinooxazolines or phosphorus amidites as ligands, provided ee values of >90%, at a catalyst loading of <0.5 mol-%, and displayed a marked preference for intra- over corresponding intermolecular reactions.
