Synthesis of mollugin

The total synthesis of mollugin, a major constituent of rubiaceous herbs, using a straightforward synthetic approach starting from 1,4-naphthoquinone via a sequence of reactions, including selective prenylation, epoxidation, reduction of the quinone moiety, acid-catalysed ring expansion, bromination, dehydration and methoxycarbonylation is presented.
