  Synthesis of Diospyrin, a Potential Agent Against Leishmaniasis and Related Parasitic Protozoan Diseases

  摘要：

  The first synthesis of diospyrin [2,6'-bis(5-hydroxy-7-methyl-1,4-naphthoquinone), Ij was achieved by employing Suzuki coupling between 5 and 14 as the key reaction to connect the two 7-methyljuglone units.

  Total Synthesis of the Antitumor–Antitubercular 2,6′-Bijuglone Natural Product Diospyrin and Its 3,6′-Isomer

  摘要：

  The 2,6'-bijuglone natural product diospyrin and its unnatural 3,6'-isomer idospyrin have been synthesized in seven steps each from N,N-diethylsenecioamide in overall yields of 12% and 13%, respectively. The syntheses diverge from ramentaceone (7-methyljuglone) and include a key Suzuki-Miyaura cross-coupling. Diospyrin, idospyrin, and several synthetic precursors exhibit potent and selective cytotoxicity to the murine myeloma NS-1 cell line over neonatal foreskin cells.
