Reaction Steps
To 40 mL of 300 mM potassium phosphate buffer, pH=6.5, containing NaCl (100 mM), DMSO (3% v:v), glucose (200 mM), and glycerol (10% v:v), 40 mM of 2-methyl-3-ketoketoglutarate diethyl ester was added along with 100 mg of lyophilized KRED 1008 and 30 mg of glucose dehydrogenase. The reaction mixture was incubated for 48 hours at 37° C. Gas chromatographic analysis showed that the yield of hydroxy diester product was greater than 80%. The product was isolated by extraction of the reaction mixture with ethyl acetate and purification using silica gel chromatography. Isolated yield was in the range of 85–95%.
