An asymmetricsynthesis of anti-aldol segments via a nonaldol route is described. The strategy involves a highly diastereoselectivesynthesis of functionalized tetrahydrofuran derivatives from opticallyactive 4-phenylbutyrolactone. Treatment of the tetrahydrofuran derivatives with a Lewis acid and acetic anhydride provided the corresponding ring-opened styrene derivatives. Oxidative cleavage of the
