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.

Synthesis of New Vitamin K Analogues as Steroid and Xenobiotic Receptor (SXR) Agonists: Insights into the Biological Role of the Side Chain Part of Vitamin K
Vitamin K2 has been demonstrated to induce gene expression related to bone formation through a nuclear steroid and xenobiotic receptor (SXR). We synthesized newvitaminK analogues with the same isoprene side chains symmetrically introduced at the 2 and 3 positions of 1,4-naphthoquinone and evaluated the transcriptional activity of the target gene. The transcriptional activity was related to the length
