A new domino oxidation—rearrangement of 2,3-dihydrowogonin to negletein

We report an expeditious, iodine-catalysed oxidation of 2,3-dihydrowogonin to negletein which comprises a Wessely–Moser rearrangement (WMR), associated not with an O-demethylation, as usual, but with an oxygen to oxygen methyl shift. In contrast, DDQ in 1

Synthesis of ring A-modified baicalein derivatives

Baicalein, an important active constituent of the traditional Chinese herb Scutellaria baicalensis, exhibited antitumor activity and inhibitory activity against P-gp 170. The syntheses of 25 baicalein derivatives, 2-26 (Table), are described here (Scheme
