Participants

Reaction Steps

Ethyl (2RS) (+/−) 2-ethoxy-3-(4-hydroxyphenyl)propanoate (0.5 g) was shaken with 60 mg of the lyophilised hydrolytic enzyme mixture from Aspergillus oryzae in 1 ml 1M phosphate buffer (pH=7) with organic co-solvents (according to the table below) at 27° C. The reaction mixture was poured into 20 ml MeOH after 4 h to stop the enzymatic reactions followed by analysis by the chiral CCE method 2.
