  Rationalisation of the stereochemical outcome of ene-reductase-mediated bioreduction of α,β-difunctionalised alkenes

  摘要：

  The OYE1-3-mediated reductions of some alpha,beta-difunctionalised alkenes, showing on the double bond a nitrile and ester group, are submitted to a careful stereochemical analysis, in order to identify which of the two electron-withdrawing groups (EWGs) is responsible for the activation of the C=C double bond towards reduction and for establishing hydrogen bond interactions within the binding pocket of the enzymes. The results show that for most of these substrates the activating EWG is the CN moiety linked to the prostereogenic olefinic carbon atom. The final stereochemical outcome can be explained through the empirical model which has been recently developed for difunctionalised alkenes activated by carbonyl/carboxyl containing EWGs.In a single case the activation is due to the COOR group linked to the less substituted olefinic carbon atom: an alternative empirical model is established for this kind of substrates, taking into consideration the OYE-catalysed reductions of beta,beta'-disubstituted-a-monofunctionalised alkenes.

  acid derivatives for foldamer chemistry applications. The stereochemical outcome of the biotransformations was carefully analysed by means of deuterium labeling experiments. The results of this analysis were employed to rationalise the effects of substrate-control on the stereoselectivity of a certain class of ene-reductase-mediated reduction reactions. A simple model was developed to describe the structural
