On September 30, 2008, Yang, Zhigang; Liu, Jie; Liu, Xiaohua; Wang, Zhen; Feng, Xiaoming; Su, Zhishan; Hu, Changwei published an article.Recommanded Product: tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate The title of the article was Highly efficient amine organocatalysts based on bispidine for the asymmetric Michael addition of ketones to nitroolefins. And the article contained the following:
A highly diastereoselective and enantioselective Michael addition of cyclohexanone, acetone and other ketones to nitroolefins was developed by the use of an amine organocatalyst based on bispidine. Addnl., a theor. study of transition structures revealed that this bispidine-based primary-secondary amine catalyst could serve through an enamine intermediate and H-bond interaction, which was important for the reactivity and selectivity of this reaction. The experimental process involved the reaction of tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate(cas: 227940-70-7).Recommanded Product: tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate
