A total synthesis of the enantiomer of anhydromyriocin (anhydrothermozymocidin)

Abstract

The optical antipode of anhydromyriocin, the γ-lactone derived from the antibiotic myriocin (thermozymocidin), was synthesized from L-arabinose, establishing the absolute configuration of myriocin as 47. In contrast to its natural enantiomer, it showed but little antifungal activity.
