  Superior substrate control on diastereoselection in boric Lewis acid-promoted aldol reactions. Asymmetric synthesis of a 3,4-syn homologous series of ethyl 3,5-dihydroxy-2,4-dimethyl-5-phenylpentanoates

  摘要：

  The BF3. OEt2-promoted aldol reaction of chiral syn- and anti-alpha -methyl-beta -siloxy aldehydes with a silyl ketene acetal resulted in essentially complete syn Felkin selection. Even in the asymmetric aldol reaction using chiral oxazaborolidinones, the substrate control with respect to diastereoselection was found to overcome the promoter (catalyst) control which would normally occur depending on the stereocenter of the chiral boranes.
