Abstract
The peroxygenase from Agrocybe aegerita (AaeUPO) has been evaluated for stereoselective oxyfunctionalization chemistry under non-aqueous reaction conditions. The stereoselective hydroxylation of ethylbenzene to (R)-1-phenylethanol was performed in neat substrate as reaction medium together with the immobilized biocatalyst and tertBuOOH as oxidant. Stability and activity issues still have to be addressed. Nevertheless, gram-scale production of enantiopure (R)-1-phenylethanol was achieved with respectable 90,000 turnovers of the biocatalyst.
