Biocatalytic synthesis of the Green Note trans-2-hexenal in a continuous-flow microreactor
Beilstein Journal of Organic Chemistry, 2018 The biocatalytic preparation of trans-hex-2-enal from trans-hex-2-enol using a novel aryl alcohol oxidase from Pleurotus eryngii (PeAAOx) is reported. As O2-dependent enzyme PeAAOx-dependent reactions are generally plagued by the poor solubility of O2 in
