  Stereocontrolled synthesis of γ-branched amino acids. TiCl4 Mediated addition of (E)-crotylsilane to N,O-protected serine aldehyde

  摘要：

  The N-Boc derivatives of (2S,3S,4R,6E)-2-amino-3-hydroxy-4-methyl-6-octenoic acid and (2S,4R)-2-amino-4-methyl-hexanoic acid have been prepared using the acetonide of D-Serine aldehyde 1 as a formyl glycine equivalent. The stereochemistry of the y-branch was introduced by reaction of (E)-crotyltrimethylsilane with 1 in the presence of TiCl4 followed by elaboration of the terminal double bond and further transformation of the Serine hydroxymethyl group into a carboxylic acid.
