• Enantioselective Synthesis of α-Alkyl,α-Vinyl Amino Acids via [2,3]-Sigmatropic Rearrangement of Selenimides
  作者：Alan Armstrong、Daniel P. G. Emmerson

  DOI：10.1021/ol1030926

  日期：2011.3.4

  Chiral α-alkyl,α-vinyl amino acids (quaternary vinyl glycine derivatives) are prepared with high levels of enantiomeric purity by [2,3]-sigmatropic rearrangement of allylic selenimides. The required trisubstituted allylic selenides are prepared by an organocatalytic α-selenenylation of aldehydes followed by Horner−Wadsworth−Emmons (HWE) olefination. Both (E)-and (Z)-geometrical isomers are available

  A simple and efficient synthesis of polystyrene-supported proline and prolinamide has been carried out. Polystyrene-supported proline has been used as organocatalyst in the asymmetric aldol reaction between cyclohexanone and substituted benzaldehydes in water without any additive. High yields, diastereoselectivities and ee values have been observed. The versatility of this resin was demonstrated in

  experimental conditions for the preparation of trimethylsilyl enol ethers 3 from α-phenylseleno aldehydes 1, compatible with a limited deselenenylation of the substrate, were studied.
