  Silylcupration of (R)-2,2-Dimethyl-3-(tert-butoxycarbonyl)-4-ethynyloxazolidine:  A Stereoselective Approach to the Synthesis of γ-Silylated Saturated and Unsaturated α-Amino Acids

  摘要：

  Enantioselective synthesis of gamma-silylated amino acids is reported, using a four-step procedure based on the silylcupration of ethynyloxazolidine 2. Silylcuprates 6a-c are highlighted as useful reagents to be employed with enantiomerically enriched substrates. Vinylsilanes 5 are easily prepared and highlighted as useful intermediates to yield the final-compounds after reduction, opening of the oxazolidine ring, and oxidation. Moreover, beta,gamma-unsaturated amino acids are obtained as very interesting vinylglycine derivatives. The capability of silicon-containing amino acids to be incorporated into dipeptides is also shown.

  摘要：

  The synthesis of enantiomerically enriched silicon containing amino acids is described. Silylcupration of 2,2-dimethyl-3-(tert-butoxycarbonyl)-4-ethynyloxazolidine, easily derived from serine aldehyde, afforded regio- and stereoselectively gamma-silylated ethenyloxazolidines of (E)-geometry as useful precursors of saturated and unsaturated gamma-silylated amino acids.
