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.

Axiallychiral tetra-ortho-substituted biaryl skeleton exists in numerous biologically important natural products, pharmaceutical molecules, chiral catalysts and ligands. The efficient synthesis of chiral tetra-ortho-substituted biaryl structures remains a challenging but unsolved problem. Among various asymmetric synthetic protocols, enantioselective Suzuki-Miyaura cross-coupling represents one of
