An efficient synthesis of the title compounds in high enantiomeric purity (>98percent) involves bromination under photolytic conditions of (2S)- or (2R)-oxazolidinones derived from (S)-alanine followed by treatment of the products with sodium iodide in re
Diastereoselective Radical Addition to Derivatives of Dehydroalanine and of Dehydrolactic Acid
Beckwith, Athelstan L. J.,Chai, Christina L. L.
, p. 1087 - 1088 (2007/10/02)
The cyclic methylene compounds (1)-(3) undergo diastereoselective free radical addition when treated with alkylmercury hydride or alkyl iodide/tributylstannane to give products useful for the enantioselective synthesis of α-amino and α-hydroxy acids.
