An organo-catalyzed enantioselective addition of selenosulfonates to α,β-unsaturated ketones was developed for the first time. With a chiral squaramide as an efficient catalyst, the desired α-selenylated ketones were obtained in a good yields with high enantioselectivity up to 89% ee, and good results could be obtained on a gram scale. The products could also be efficiently transformed into useful
首次开发了将硒代磺酸酯有机催化对映体加成到α,β-不饱和酮上的方法。使用手性方酰胺作为有效的催化剂,以良好的收率和高达89%ee的高对映选择性获得了所需的α-硒化酮,并且以克为单位可以获得良好的结果。产品也可以有效地转化为具有丙烯基立体中心的有用的结构单元;本研究中提出的策略可能会在有机合成中找到更多的应用。
