摘要

A five-step and protecting group free synthesis of (±)-columbianetin from cyclohexane-1, 3- dione is reported. The former compound was converted into its p-hydroxycinnamate derivative,(±)-angelmarin, using Coster's esterification procedure. Efforts to modify the synthesis so as to prepare angelmarin and columbianetin in an enantioselective manner are described.
