  Chemoenzymatic synthesis and application of a new, easily chiral auxiliary for the synthesis of peptidomimetics via an Ugi reaction

  摘要：

  A new chiral auxiliary derived from alpha-phenylethylamine, alpha-(2,4-dimethoxyphenyl)ethylamine is presented. It significantly expands upon the application of cc-phenylethylamine derivatives used as chiral auxiliaries. A straightforward, chemoenzymatic synthesis of non-racemic alpha-(2,4-dimethoxyphenyl)ethylamine is described and the new chiral auxiliary applied to an asymmetric Ugi reaction. The mild conditions used for the cleavage of the auxiliary allowed to obtain chiral, non-racemic peptidomimetics possessing reactive alpha,beta-unsaturated double bonds.(C) 2014 Elsevier Ltd.
