Asymmetric Reduction of Prochiral Ketones to Chiral Alcohol by Photo-Biocatalysis with Microalgae
Abstract:
The photo-biocatalytic ability of eukaryotic microalgae and prokaryotic microalgae on nonnatural prochiral ketones to produce chiral alcohols was studied in this paper. The results proved that ethyl acetoacetate and acetophenone can be stereo-selectively reduced to the corresponding ethyl S-3-hydroxybutyrate (EHB) and S-1-phenylethanol (PEA) by microalgal photo-biocatalysis with high enantioselectivity, respectively. Scenedesmus obliquus has the best photo-biocatalytic activity to ethyl acetoacetate reduction reaction among the two selected eukaryotic microalgae, about 43.98% yield and 69.58% e.e. achieved. Spirulina platensis is the best biocatalyst to acetophenone among the four selected prokaryotic microalgae, about 52.65% yield and 99.40% e.e. achieved.
