Reaktionsschritte
The mixture of 5.0 g (25.7 mmol) of ethyl 3-phenyl-3-hydroxypropionate, 1.83 g (13 mmol) of vinyl caproate and 1.0 g of lipase PS was stirred at room temperature for 35 hours. After the lipase was removed by filtration, the filtrate was eluted by column chromatography (eluting solution; 9/1 of toluene/ethyl acetate) to obtain 2.2 g (>99%ee) of (-)-ethyl 3-phenyl-3-hydroxypropionate and 4.1 g (about 90%ee) of (+)-ethyl 3-phenyl-3-hexanoyloxypropionate.
