TsOH-Catalyzed reactions of 6,7-disubstituted 2-hydroxynaphthazarins and acyclic or cyclic α,β-enones afforded the corresponding Michael-type adducts, viz., 3-substituted naphthazarins in 17–78% yields. 1H and 13C NMR and IR spectroscopy showed t

Reflux of isopropenyl acetate with an excess of AlCl3 in 1,2-dichloroethane affords 3,5-diacetyl-2,6-dimethyl-4H-pyran-4-one in 17% yield. The mild acidic cleavage of the latter (2% HCl, 20 °C, 16 h) gives 3-acetyl-2,6-dimethyl-4H-pyran-4-one in 87%

It is shown that the Michael-type adducts with cyclohexanone or methyl vinyl ketone at C-3 exist as a mixture of open-chain and cyclic tautomers in CDCl3 solutions, whereas adducts with cyclopentanones at C-3 exist only in the open-chain form.
