Synthesis of 3-CF(2)-Containing Chromones via a Visible-Light-Induced Radical Cascade Reaction of o-Hydroxyaryl Enaminones
[Image: see text] A general and efficient visible-light-induced CF(2) radical-based cascade reaction of o-hydroxyaryl enaminones has been described. This protocol afforded the corresponding functionalized 3-CF(2)-containing chromones in generally good yields under mild reaction conditions. The use o...

description | [Image: see text] A general and efficient visible-light-induced CF(2) radical-based cascade reaction of o-hydroxyaryl enaminones has been described. This protocol afforded the corresponding functionalized 3-CF(2)-containing chromones in generally good yields under mild reaction conditions. The use of NaHSO(3), which has both basicity and reducibility, efficiently suppressed the formation of two byproducts, 4H-chromen-4-one and 3-bromo-4H-chromen-4-one. |
