  Amino Acid-Based Synthesis of Trifluoromethylalkene Dipeptide Isosteres by Alcohol-Assisted Nucleophilic Trifluoromethylation and Organozinc−Copper-Mediated S_N2′ Alkylation

  摘要：

  A novel synthetic approach to Xaa-Yaa-type (Z)-trifluoromethylalkene dipeptide isostere (CF3-ADI) has been developed. Starting from readily available L-phenylalanine and L-alanine, several CF3-ADIs were obtained through nucleophilic trifluoromethylation of gamma-keto esters and S(N)2' alkylation of trifluoromethylated mesylates. The influence of a trifluoromethyl group on the diastereoselectivity of the S(N)2' reaction is also discussed.
