A convergent synthesis applicable to the preparation of oxidized prenylchalcones is reported that relies on key Claisen–Schmidt, Mitsunobu, and vinyl/benzyl Stille coupling operations. The synthetic strategy was applied towards the preparation of t

A short, scalable route to 4‐hydroxymethylcyclopent‐2‐enone, based upon a silicon‐directed Nazarov cyclization, is described. Noteworthy in this study is the success of the cyclization with an oxygenated substrate.

Advanced C-prenylated intermediates for three aromatase inhibitors, including morachalcone A, can be synthesized through a Claisen–Schmidt condensation followed by Florisil®-catalyzed [1,3]-sigmatropic rearrangement of a prenyl phenyl ether.

The nonsteroidal anti-inflammatory drugs flurbiprofen and ibuprofen were modified in an attempt to alter the kinetics of inhibitor binding by COX-1. Contrary to prior predictions, a halogen substituent is not sufficient to confer slow tight-binding b

The biosynthetic pathway to the potent mycotoxin aflatoxin B1 is unusually long and complex, proceeding from anthraquinone to xanthone to coumarin nuclear types bearing fused tetrahydro- and bisdihydrofuran rings. A synthetic strategy is described in

The absolute configuration of the dihydrobisfuran ring system characteristic of aflatoxin B1 is essential to the covalent reaction of its metabolically activated form with double-stranded DNA. The biosynthesis of this potent mycotoxin proceeds throug
