The enantioselective reductive cyclization of gamma-chloro N-(tert-butanesulfinyl)ketimines towards the short and efficient synthesis of (S)- and (R)-2-arylpyrrolidines (ee >99%) is described for the first time by treatment with LiBEt(3)H and subsequent acid deprotection.
首次报道了通过手性叔丁基亚磺酰基氯代烯胺的对映选择性还原环化反应,以高效、短捷的方式合成(S)-和(R)-2-芳基吡咯烷(ee>99%)。该反应使用 LiBEt(3)H 处理,随后进行酸脱保护。
