  Highly Stereoselective TiCl₄-Catalyzed Evans−Aldol and Et₃Al-Mediated Reformatsky Reactions. Efficient Accesses to Optically Active syn- or anti-α-Trifluoromethyl-β-hydroxy Carboxylic Acid Derivatives

  摘要：

  The TiCl4-catalyzed Evans-aldol reaction of optically active 3,3,3-trifluoropropanoic imide gave the non-Evans syn product stereoselectively, whereas the Reformatsky reaction of 2-bromo-3,3,3-trifluoropropanoic imide in the presence of Et3Al led to the Evans anti product. These new approaches enabled us to synthesize all stereoisomers of trifluoromethylated aldol products for the first time.

  Total synthesis of γ-trifluoromethylated analogs of goniothalamin and their derivatives

  摘要：

  An efficient method for the construction of chiral gamma-trifluoromethylated alpha,beta-unsaturated delta-lactone, a widely existing pharmacophore, has been developed and successfully applied for synthesis of gamma-trifluoromethylated goniothalamins. The key steps included Evans-Aldol reaction of chiral titanium enolate of alpha-CF3 imide, Wittig olefination and lactonization. The transformation of gamma-trifluoromethylated alpha,beta-unsaturated delta-lactone to a series of trifluoromethylated styryllactones was also investigated. (C) 2013 Elsevier B.V.
