Isolation, Structure, and Synthesis of Combretastatin C-1

A new cell growth inhibitory (PS ED50 2.2 μg/mL) phenanthraquinone designated combretastatin C-1 (2) has been isolated from the African tree Combretum caffrum.The structure (2) assigned combretastatin C-1 was based on high-resolution mass and NMR spectral analyses and confirmed by total syntheses.Synthetic routes 5b -> 6b -> 2 and especially 5c -> 6c -> 2 proved to be quite practical.

Synthesis of the Pterocarpan Constituents of Swartzia laevicarpa

The synthesis of 2,8-dihydroxy-3,4-dimethoxy- (1), 2,8-dihydroxy-3,9,10-trimethoxy- (2), 8-hydroxy-3,4,9,10-tetramethoxy- (3), and 2,8-dihydroxy-3,4,9,10-tetramethoxypterocarpan (4) - each of them as racemate - confirmed the constitution of four new ptero
