A novel, highly stereoselective route for pharmaceutically relevant octahydroindole-2-carboxylates bearing a quaternary stereocenter has been developed. The key chiral intermediates 3 have been prepared in good yields and enantiomeric excesses up to 98%. A broad substrate range has been tolerated under the reaction conditions.
已开发出具有季立体中心的药学上相关的八氢
吲哚-2-羧酸酯的新颖的,高度立体选择性的途径。关键的手性中间体3的制备得率很高,对映体过量高达98%。在反应条件下可以耐受较宽的底物范围。
