Acylation and palladium-mediated couplings of maltol, a biobased γ-pyrone
Qu, Yang,Ananin, Aleksei V.,Kraus, George A.
, (2020)
Maltol triflate 3 undergoes palladium-mediated carbon-carbon bond formation with styrene, boronic acids and alkynes. Benzyl ether 2 can be acylated. The acylation products can be readily converted into furo[3,2-b]pyranones.
Thallium(III) p-tosylate mediated oxidative rearrangement in substituted chromanones: A novel approach to the synthesis of substituted chromones and tetrahydroxanthones

On treatment with thallium(III) p-tosylate, subtituted chromanones undergo smooth dehydrogenation to afford substituted chromones while 2,2-dialkylchromanones undergo oxidative 2,3-alkyl migration to yield 2,3-dialkylchromones in high yields.The migratory aptitude of different alkyl groups with respect to methyl group has also been studied. 2-Spirochromanones undergo oxidative 2,3-alkyl migration to afford tetrahydroxanthones which on dehydrogenation with DDQ afford xanthones in good yields.
