The oxytriazole catalyst “pyrrolidine-HOBt” developed for asymmetric Michael addition of cyclohexanone to nitroolefins is now evaluated for the asymmetric Michael addition of aldehydes to nitroolefins under similar reaction conditions. The results of this
A solution to achieve good reusability of MNPs Fe3O4-supported (S)-diphenylprolinoltrimethylsilyl ether catalysts in asymmetric Michael reactions
Wu, Tao,Feng, Dandan,Xie, Bing,Ma, Xuebing
, p. 25246 - 25254 (2016/03/22)
A new supported (S)-diphenylprolinol trimethylsilyl ether (Fe3O4/PVP@SiO2/ProTMS) using polyvinylpyrrolidone (PVP)-modified MNPs Fe3O4 as a support was prepared via one-pot surface-modification, and e

, p. 1286 - 1291 (2015/01/09)
An effective protocol for the stereoselective Michael addition of aldehydes to nitroolefins using pyrrolidine-pyrazole as an organocatalyst is described. The catalytic cycle was found to be productive in terms of yield and selectivity, when performed unde
Highly efficient asymmetric Michael addition of aldehydes to nitroalkenes with 4,5-methano-l-proline as organocatalysts
Yu, Han,Liu, Mouming,Han, Sheng
, p. 8380 - 8384 (2015/03/05)
The 4,5-methano-l-prolines were used as chiral organocatalysts in asymmetric Michael addition of aldehydes to nitroolefins. These proline-like catalysts are unique for their rigid bicyclic structure with a cyclopropane and two H atoms attached to the brid
Organocatalyzed stereoselective construction of N-formylpiperidines via a Michael-aza-Henry-hemiaminalization reaction cascade
Chawla, Ruchi,Rai, Ankita,Singh, Atul K.,Yadav, Lal Dhar S.
, p. 5323 - 5326 (2012/10/30)
An efficient asymmetric synthesis of N-formylpiperidines via an organocatalytic Michael-aza-Henry-hemiaminalization reaction cascade of an aldehyde, a nitroalkene, and an N-arylideneformamide is reported. The reaction is triggered by diphenylprolinol trim
Highly efficient asymmetric Michael addition of aldehyde to nitroolefin using perhydroindolic acid as a chiral organocatalyst
Zhao, Lina,Shen, Jiefeng,Liu, Delong,Liu, Yangang,Zhang, Wanbin
supporting information, p. 2840 - 2846 (2012/11/07)
Perhydroindolic acids, the by-products obtained in the industrial production of a trandolapril intermediate, were used as chiral organocatalysts in asymmetric Michael addition reactions of aldehydes to nitroolefins. These proline-like catalysts are unique
