  Enantioselective Synthesis of α-Fluoro-β³-amino Esters: Synthesis of Enantiopure, Orthogonally Protected α-Fluoro-β³-lysine

  摘要：

  The scope of a tandem conjugate addition fluorination sequence performed on alpha,beta-unsaturated esters using the enantiopure lithium amide derived from (S)-N-benzyl-N-(alpha-methylbenzyl)amine, and the electrophilic fluorinating agent N-fluorobenzenesulfonimide has been investigated. Using this method, a-fluoro-beta(3)-amino esters can be obtained in up to quantitative yield and 80:20 to >99:1 dr. This simple methodology does not rely on the use of alpha-amino acids from the chiral pool and thus provides the potential for the preparation of enantiopure alpha-fluoro-beta(3)-amino acids with a wide variety of side chains. Its utility was demonstrated through the synthesis of orthogonally protected (2S,3S)-alpha-fluoro-beta(3)-lysine.
