We present here the results obtained in our study on organocatalytic enantioselective Michael addition reaction of acetone to different nitroolefines using (2R,3aS,7aS)-octahydroindole-2-carboxylic acid [(R,S,S)-Oic] as a new and suitable catalyst for this process. Computational calculations support the results obtained with (R,S,S)-Oic versus its diastereomeric form (S,S,S)-Oic. The final products are obtained in good yields and moderate enantioselectivities (up to 58% ee).
我们在此展示了我们研究的结果,该研究涉及使用(2R,3aS,7aS)-八
氢吲哚-2-羧酸[(R,S,S)-Oic]作为一种新的合适
催化剂,对不同亚硝基
烯进行有机催化手性选择性的迈克尔加成反应,其中的反应物为
丙酮。计算结果支持了(R,S,S)-Oic与其异构体(S,S,S)-Oic的比较。最终产品以良好的收率和适中的手性选择性(最高可达58% ee)获得。
