ChemInform Abstract: 1,4-Conjugate Addition of 2-Hydroxynaphthazarins to Acyclic and Cyclic [alpha],[beta]-Unsaturated Ketones. Prototropic Ring-Chain Tautomerism of the Adducts
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. [PUBLICATION ABSTRACT]
