The ex-chiral pool synthesis of the Theodorakis C3–C11 fragment of borrelidin (1) by a chemoenzymatic approach in nine steps and 12 % overall yield starting from enantiopure methyl-branched preen gland wax esters is described. In the initial reaction, the wax ester was (ω-1)-hydroxylated regioselectively by using a mutant of the cytochrome P450 monooxygenase CYP102A1 as biocatalyst. The fourthstereocenter
