(R)-3-Hydroxy-5-(4-fluorophenyl)valeryl-CoA → 3-Hydroxy-5-phenoxypentanoic acid

Participants

Reaction Steps

Then, (R)-3-hydroxy-5-(4-fluorophenyl) valeryl CoA prepared in Reference Example 3 was added at a final concentration of 5 mM, and was incubated at 37° C. for 25 minutes, followed by adding to this pigment dispersion (R)-3-hydroxy-5-phenoxyvaleryl CoA (prepared by the method described in Eur. J. Biochem., 250, 432-439 (1997) after obtaining 3-hydroxy-5-phenoxyvaleric acid by hydrolyzing 3-hydroxy-5-phenoxyvalerate obtained by Reformatsky reaction with zinc, using as raw materials 3-phenoxypropanal synthesized by the method described in J. Org. Chem., 55, 1490-1492 (1990) and ethyl bromoacetate) so that the final concentration was 1 mM, then incubating the same at 37° C. for 5 minutes. After the reaction, electrophoretic particles were collected and suspended with kerosene as a dispersion medium in a same manner as Example 2.
