Bioactivities of quinoides 1–5 and VEGFR2 TKIs 6–10 in hepatocellular cancer (HCC) and cancer stem cells (HCSCs) were studied. Quinoide 3 was able to eradicate cancer stem cells.

highly stereocontrolled preparation, on a large scale, of two new Wieland−Miescher-type diketones is described. The approach centers on a diastereoselective Diels−Alder reaction using a new enantiomericallypure sulfinylquinone. Mechanistic investigations of this cycloaddition on several dienes are described.
