Extractive biocatalysis in the asymmetric reduction of α-alkyl, β-aryl enones by Baker’s yeast
摘要:
We prepared various chiral alpha-alkyl, beta-aryl ketones with good to excellent enantiomeric excess through the Baker's yeast asymmetric double-bond reduction of the corresponding alpha,beta-unsaturated substrates adsorbed onto the resin Amberlite XAD-7. This methodology was compatible with substrates bearing both electron-donating and withdrawing groups attached to the aromatic ring. Elongation of the alpha-alkyl substituent of the starting material strongly affected the reactivity and enantioselectivity of the reaction. (C) 2017 Elsevier Ltd. All rights reserved.

Bio-catalytic reactions involving ene-reductases (EREDs) in tandem with chemo-catalysis in water can be greatly enhanced by the presence of nanomicelles derived from the surfactant TPGS-750-M. Transformations are provided that illustrate the variety of sequences now possible in 1-pot as representative examples of this environmentally attractive approach to organic synthesis.
