Significance

Recombinant alcohol dehydrogenase-10 from the hyperthermophile Solfolobus solfataricus (SsADH-10) effects efficient dynamic reductive kinetic resolution of 2-arylpropanals. The reaction is performed at 80 ˚C using NADH as the catalytic reductant and 5% EtOH as the stoichiometric reductant. Success depends on the rapid equilibration of the 2-arylpropanal substrates (e.g. A) under the basic reaction conditions (pH 9). Only one of twelve substrates examined failed to react. The yields ranged from 55-99% and the er was generally >95:5.
