Description 923-927
A practical and effective approach towards the synthesis of 3-hetroaryl-4H-chromen-4-ones by the oxidative rearrangement
of the respective 2-hetroaryl chroman-4-ones using thallium(III) p-tosylate is described. The oxidative rearrangement of α
and β-naphthyl and thiophene behave like aryl groups. However, pyridyl groups give only the dehydrogenated product.
