Abstract

Three natural ent-halimanolides have been synthesized from ent-halimic acid. Their structures have been confirmed as well as their absolute configurations established. Bestmann methodology has been used for the synthesis of butenolides and for the synthesis of γ-hydroxybutenolides the Boukouvalas method has been employed.
