Using chiral 2-chloro-1,1,2,2-tetrafluoroethane-1-sulfinamide as the auxiliary, an efficient one-pot procedure for the asymmetric reductive amination of ketones was achieved in the presence of sodium borohydride. Both aromatic and aliphatic ketones reacted well to give the corresponding sulfinyl amides in good yields with excellent diastereoselectivities.
使用手性2-氯-1,1,2,2-四氟乙烷-1-亚磺酰胺作为辅助剂,在硼氢化钠存在下,实现了用于酮的不对称还原胺化的有效一锅法。芳族酮和脂族酮均反应良好,以良好的收率和优异的非对映选择性,得到相应的亚磺酰基酰胺。
