An atom economical and metal‐free, one‐pot two‐step asymmetric synthesis of highly valuable 2‐amino‐1‐arylethanols has been established from commercially available starting materials. The effectiveness and scalability of our approach have been demonstrated via the synthesis of the Salbutamol acetate salt, a bronchodilator widely used to treat asthma.

The one-pot protocol involving the in situ generation of α-amino ketones via the nucleophilic substitution of α-bromoketones with amines and the Ir-catalyzed asymmetric hydrogenation of ketone intermediates was developed for the asymmetric synthesis of a diverse array of chiral β-amino alcohols with excellent results.
一锅法涉及通过用胺亲核取代 α-溴酮原位生成 α-氨基酮和 Ir 催化的酮中间体不对称氢化,用于不对称合成多种手性 β-氨基醇类,效果极佳。
