Organocatalytic asymmetric allylic carbon-carbon bond formation
Poulsen, Thomas B.,Bell, Mark,Jrgensen, Karl Anker
, p. 63 - 70 (2006)
Organocatalytic allylic C-C bond-forming addition of activated alkylidenes to alkyl and aryl nitroalkenes has been achieved with high diastereo- and enantioselectivity. Chiral tertiary amine catalysts are used to give allyl intermediates which exhibit γ-s

Chen, Wei-Yi,Ouyang, Luo,Chen, Rui-Ye,Li, Xin-Sheng
experimental part, p. 2585 - 2594 (2012/07/28)
(Chemical Equation Presented) The self-assembled organocatalyst of cinchona alkaloid derivatives and amino acids has been applied to a direct asymmetric vinylogous Michael addition of α,α-dicyanoolefins to nitroolefins; the corresponding products could be obtained in moderate to good yields and enantioselectivities.

Asymmetric direct vinylogous carbon-carbon bond formation catalyzed by bifunctional organocatalysts
Jiang, Lin,Zheng, Hong-Ting,Liu, Tian-Yu,Yue, Lei,Chen, Ying-Chun
, p. 5123 - 5128 (2008/02/01)
The bifunctional chiral thiourea-tertiary amine organocatalysts have been applied to a direct asymmetric vinylogous Michael addition of α,α-dicyanoolefins to nitroolefins with 2-10 mol % catalyst loadings. The electronic properties of the thiourea-based c
Asymmetric direct vinylogous michael reaction of activated alkenes to nitroolefins catalyzed by modified cinchona alkaloids
Xue, Dong,Chen, Ying-Chun,Wang, Qi-Wei,Cun, Ling-Feng,Zhu, Jin,Deng, Jin-Gen
, p. 5293 - 5296 (2007/10/03)
(Chemical Equation Presented) The first organocatalytic and asymmetric direct vinylogous Michael reaction that employs the electron-deficient vinyl malononitriles as the nucleophilic species has been reported. The novel transformations exhibit exclusive γ
