  Toward Asymmetric Aldol-Tishchenko Reactions with Enolizable Aldehydes: Access to Defined Configured Stereotriads, Tetrads, and Stereopentads

  摘要：

  Asymmetric aldol-Tishchenko, reactions of enolizable aldehydes and ketones in the presence of chiral BINOLTi(OtBU)(2)/Cinchona alkaloids complexes are described. Different configurative outcomes of these reactions depend on an equilibration through a retro aldol/aldol sequence and can be influenced by the configurative architecture of substrates. The results are explained by means of transition state models and rate constants. These considerations offer a fine-tuning of diastereoselectivity in aldol-Tishchenko reactions. Extensions of this research give access to defined configured stereotriads, stereotetrads, and stereopentads.
