unprecedented aninoic Ir-f-phamidol catalyst for asymmetric hydrogenation of γ-amino ketones followed by stereoselective cyclization for construction of valuable chiral 2-aryl-pyrrolidine pharmacophores. The Ir-f-phamidol catalyst showed up to 1,000,000 TON and >99% ee, as well as excellent tolerance of substrates and protecting groups, providing various chiral amino alcohol intermediates. Upon optimization of
具有百万周转数和优异选择性的过渡金属催化剂鲜有报道,但对于光学纯药物、天然产物和精细化学品的工业制造至关重要。在本文中,我们报道了一种前所未有的阴离子Ir-f-phamidol催化剂,用于γ-氨基酮的不对称氢化,然后进行立体选择性环化,以构建有价值的手性2-芳基-吡咯烷药效团。 Ir-f-phamidol 催化剂表现出高达 1,000,000 TON 和 >99% ee,以及优异的底物和保护基耐受性,可提供各种手性氨基醇中间体。优化条件后,立体选择性环化反应非常顺利和高效(定量转化率,92% 至 >99% ee)。最后,将该溶液应用于含有此类手性2-芳基-吡咯烷药效团的高价值手性实体的制备。
