Katakawa, Kazuaki published the artcileSelective Synthesis of Benzyl Enol Ethers of β-Dicarbonyl Compounds in Basic Condition and the Application towards Synthesis of Naphthoquinones, Safety of Triisopropylsilanol, the publication is Heterocycles (2014), 88(1), 817-825, database is CAplus.
Selective synthesis of benzyl enol ether of β-tetronic acids and β-dicarbonyl compounds in basic condition was examined The benzylation of α-methyl-β-tetronic acid with benzyl tosylate in the presence of potassium carbonate selectively gave the benzyl enol ether. The reaction of β-tetronic acid and cyclic 1,3-diketones also gave the O-benzyl adducts preferentially over C,O-dibenzylation. The Diels-Alder reactions of furans derived from the benzyl enol ether of α-methylβ-tetronic acid and benzyne gave functionalized naphthoquinones I (R = PhCH2, H).
