Abstract

The stereoselective synthesis of a seco-acid derivative of lepranthin (1), a lichen-produced unique 16-membered dimeric macrolide, is described wherein all asymmetric carbon centers were constructed in a highly stereoselective manner, respectively, by using different epoxide-opening reactions of the α,β-unsaturated γ,δ-epoxy ester system and an epoxy alcohol derivative as the key steps.
