Synthesis of enantiomerically pure α-ethyl, α-vinyl and α-ethynyl 3,3,3-trifluoro alaninates
摘要:
We describe the first synthesis of enantiomerically pure (S)-alpha-vinyl and (S)-alpha-ethynyl 3,3,3-trifluoro alanine (TF-Ala) ethyl esters, starting from the in situ generated sulfinimine (S)-2 as key fluorinated building-block. (S)-alpha-Ethyl TF-Ala-OEt has been prepared as well by this route. (C) 2004 Elsevier B.V. All rights reserved.
