Majee, Debashis; Jakkampudi, Satish; Arman, Hadi D.; Zhao, John C.-G. published the artcile< Enantioselective Synthesis of Cyclohexenol Derivatives from γ-Aryl-Substituted Enals via an Organocatalyzed Three-Component Reaction>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is cyclohexenol preparation enantioselective diastereoselective; unsaturated aldehyde nitroalkene cinchona alkaloid squaramide catalyst.
A three-component reaction between γ-aryl-substituted α,β-unsaturated aldehydes and nitroalkenes was realized by using cinchona alkaloid-derived (thio)ureas and squaramides via the dienolate intermediates. This unprecedented 1,3- and 1,5-reactivity of dienolates of the γ-aryl-α,β-unsaturated aldehydes led to the formation of cyclohexenol derivatives I (R1 = Ph, 4-MeOC6H4, 4-FC6H4, etc.; R2 =Ph, 2-BrC6H4, 2-theinyl, etc.) with four contiguous stereogenic centers and a chiral substituent at C2 with good diastereoselectivities and high ee values. Such reactivities of the dienolates are totally different from those of the corresponding dienamine intermediates.
Organic Letters published new progress about Alkenes, nitro Role: RCT (Reactant), RACT (Reactant or Reagent). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate.
