Deracemization of (RS)-1-[(4-methylselanyl)phenyl]ethanol and (RS)-1-[(4-ethylselanyl)phenyl]ethanol by strains of Aspergillus terreus
The fungal strains Aspergillus terreus URM 3371 and A. terreus CCT 4083, isolated in Brazil, catalysed the deracemization of (RS)-1-[(4-methylselanyl)phenyl]ethanol (1) and (RS)-1-[(4-ethylselanyl)phenyl]ethanol (2). Different mass of whole fungal cells (1–5 g), pH values (4 and 7), biotransformatio...

Different mass of whole fungal cells (1–5 g), pH values (4 and 7), biotransformation temperature (20 and 32 °C) and additives (ethanol, butanol, propanol and cyclohexanol) were employed in attempt to improve product yield and selectivity. The A. terreus strain URM 3371 transformed (RS)-1 into (+)-(R)-1 with high enantiomeric excess (e.e.³98 %), good conversion (³98 %) and acceptable yield (53 %) | ||
