Coupling of 4-bromo-1-butene (I) with catecholborane (II) afforded the bromobutyl boronate (III). Subsequent exchange of (III) with alpha-pinanediol (IV) produced (V), which was regioselectively chlorinated to give (VI). Displacement of the chlorine atom of (VI) with lithium hexamethyldisilazide, followed by acid treatment furnished intermediate (VII).
