Spiral binding: A highly enantioselective hydrogenation of unsaturated heterocyclic acids has been developed by using chiral iridium/spirophosphino oxazoline catalysts (see scheme; BArF(-) =tetrakis[3,5-bis(trifluoromethyl)phenyl]borate, Boc=tert-butoxycarbonyl). This reaction provided an efficient method for the preparation of optically active heterocyclic acids with excellent enantioselectivities.
通过使用手性铱/螺环膦恶唑啉催化剂(见方案;BArF(-) =四[3,5-双(三氟甲基)苯基]硼酸盐,Boc=叔丁氧羰基),开发了一种高度对映选择性的不饱和杂环酸氢化方法。该反应为制备具有优异对映选择性的光学活性杂环酸提供了一种有效的方法。
