“…The use of the intact plant system instead of plant cells or isolated enzymes offers several considerable advantages: Their availability at low cost, they are easily disposable as biodegradable, and they have mild reaction conditions. The easy preparation of the reactive system makes the use of comminuted plant material as a biocatalyst an attractive economic alternative [18]. Plant biocatalysts have been applied primarily in the reduction of ketones.…”

Plant-Mediated Enantioselective Transformation of Indan-1-One and Indan-1-ol

et al. 2019

The main purpose of this work was to discover the way to obtain pure enantiomers of indan-1-ol. The subject of the study was the ability of the plant enzyme system to reduce the carbonyl group of indan-1-one, as well as to oxidize the hydroxyl group of racemic indan-1-ol. Locally available fruit and vegetables were selected for stereoselective biotransformation. During the reduction, mainly alcohol of the S-(+)-configuration with a high enantiomeric excess (ee = 99%) was obtained. The opposite enantiomer was obtained in bioreduction with the apple and parsley. Racemic indan-1-ol was oxidized by all catalysts. The best result was obtained for the Jerusalem artichoke: Over 50% conversion was observed after 1 h, and the enantiomeric excess of unreacted R-(–)-indan1-ol was 100%.
