Enantioselective synthesis of β-amino alcohols from 1,2-diols by the use of [RuCl2(p-cymene)]2/(S,R)-JOSIPHOS catalysis was developed. Several 1,2-diols were treated with secondary amines to afford the corresponding optically active β-amino alcohols in up to 99 % yield with 77 % ee.
开发了使用 [RuCl2(p-cymene)]2/(S,R)-JOSIPHOS 催化从 1,2-二醇对映选择性合成 β-氨基醇。几种 1,2-二醇用仲胺处理,得到相应的光学活性 β-氨基醇,产率高达 99%,ee 为 77%。
