Xue, Dong; Chen, Ying-Chun; Wang, Qi-Wei; Cun, Ling-Feng; Zhu, Jin; Deng, Jin-Gen published the artcile< Asymmetric Direct Vinylogous Michael Reaction of Activated Alkenes to Nitroolefins Catalyzed by Modified Cinchona Alkaloids>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is malononitrile alkylidene stereoselective vinylogous Michael addition nitroalkene cinchona alkaloid; alkylidene malononitrile nitroalkyl asym synthesis.
The first organocatalytic and asym. direct vinylogous Michael reaction of electron-deficient alkylidene malononitriles, e.g. I (X = CH2, O, S), as the nucleophilic species with nitroalkenes RCH:CHNO2 (R = Ph, 4-MeOC6H4, 4-ClC6H4, 2-furyl, 2-thienyl, etc.) has been reported. The novel transformations exhibit exclusive γ-selectivity and high diastereo- and enantioselectivity and afford the multifunctional products with two vicinal chiral centers, e.g. II, in 85-95% yields.
Organic Letters published new progress about Alkenes, electron-deficient Role: RCT (Reactant), RACT (Reactant or Reagent). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
