Abstract

From stereoisomeric α, β-unsaturated nitriles (E, Z)-1, the recombinant nitrilase AtNIT1 from Arabidopsis thaliana hydrolyses the (E)-isomers exclusively to the corresponding (E)- carboxylic acids (E)-2 with high specificity. The (E)-selectivity can also be utilised for the preparation of the isomerically pure nitriles (Z)-1. From (E, Z)-2-hydroxycinnamonitrile (E, Z)- 3, the otherwise difficult obtainable (Z)-3 was prepared in 66% isolated yield. With β, γ- ...
