Matviitsuk, Anastassia; Greenhalgh, Mark D.; Taylor, James E.; Nguyen, Xuan B.; Cordes, David B.; Slawin, Alexandra M. Z.; Lupton, David W.; Smith, Andrew D. published the artcile< Unanticipated Silyl Transfer in Enantioselective α,β-Unsaturated Acyl Ammonium Catalysis Using Silyl Nitronates>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is isothiourea catalyzed addition silyl nitronate unsaturated ester; crystal structure silylmorpholinylnitropentanoate nitrobutanylsilylsuccinate; mol structure silylmorpholinylnitropentanoate nitrobutanylsilylsuccinate.
The use of silyl nitronates is reported for the isothiourea-catalyzed synthesis of γ-nitro-substituted silyl esters containing up to two contiguous stereocenters in good yields with excellent enantioselectivities (up to 93% yield and 99:1 er). The serendipitously discovered formation of silyl ester products in this reaction demonstrates a novel platform for catalyst turnover in α,β-unsaturated acyl ammonium catalysis.
Organic Letters published new progress about Anhydrides, unsaturated Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate.
