ferrocene aminophosphoxazoline ligands (f-amphox) have been successfully developed and used in iridium-catalytic asymmetric hydrogenation of simple ketones to afford corresponding enantiomerically enriched alcohols under mild conditions with superb activities and excellent enantioselectivities (up to 1 000 000 TON, almost all products up to >99% ee, full conversion). The resulting chiral alcohols and their
已经成功开发了一系列模块化且富电子的三齿二茂铁氨基磷恶唑啉配体(f-amphox),并用于铱在铱催化的不对称加氢中进行简单的酮加氢,以在温和的条件下提供相应的对映异构体富集的醇,具有出色的活性和出色的对映选择性(最高1 000 000 TON,几乎所有产品的ee都> 99%,完全转换)。所得的手性醇及其衍生物是药物中的重要中间体。
