As an extension of structure/activity investigations of resveratrol (1), phenstatin (2c), and the cancer antiangiogenesis drug sodium combretastatin A-4 phosphate (2b), syntheses of certain related stilbenes (14) and benzophenones (16) were undertaken. The trimethyl ether derivative of (Z)-resveratrol (4a) exhibited the strongest activity (GI50 = 0.01-0.001 μg/mL) against a minipanel of human cancer cell lines. A monodemethylated derivative (14c) was converted to prodrug 14n (sodium resverastatin phosphate) for further biological evaluation. The antitubulin and antimicrobial activities of selected compounds were also evaluated.

Efficient asymmetric Suzuki-Miyaura coupling reactions are employed for the first time in total syntheses of chiral biaryl natural products korupensamine A and B in combination with an effective diastereoselective hydrogenation, allowing ultimately a concise and stereoselective synthesis of michellamine B. Chiral monophosphorus ligands L1-3 are effective for the syntheses of a series of functionalized chiral biaryls by asymmetric Suzuki-Miyaura coupling reactions in excellent yields and enantioselectivities (up to 99% ee). The presence of a polar-π interaction between the highly polarized BOP group and the extended π system of arylboronic acid coupling partner is believed to be important for the high enantioselectivity.
