A stereodivergent approach to syn- and anti-β-hydroxy-γ-amino acids. Enantioselective synthesis of N-Boc-statine and N-Boc-3-epistatine mediated by sulfoxides
摘要:
Asymmetric syntheses of the syn- and anti-stereoisomers of N-Boc statine, based on the stereodivergent reduction of a single sulfoxide 5, derived from N-Boc-L-leucine, are reported. (C) 2003 Elsevier Science Ltd. All rights reserved.

available (S)-alanine derivatives is reported. The key step of the synthetic sequence is the conversion of γ-amino sulfoxides into γ-amino alcohols by treatment with TFAA and sym-collidine. The efficiency of this non-oxidative Pummerer reaction (NOPR) is dependent on the stereochemistry of the starting sulfoxide.
