- Efficient two directional syntheses of a homophthalate ester and novel resorcylate oligomers
-
Thermolysis of 6,6′-(2-oxopropane-1,3-diyl)bis(2,2-dimethyl-4H-1,3- dioxin-4-one) in the presence of methanol gave a triketo-ester which subsequently aromatized to provide a synthetically useful homophthalate ester. Enolate C-acylation in the presence of diethylzinc was used to synthesize other double diketo-dioxinones, which on cyclization, aromatization and dioxinone ring opening gave novel double resorcylate derivatives.

- Synthesis of 4-hydroxy- and 2,4-dihydroxy-homophthalates by [4+2] cycloaddition of 1,3-bis(silyloxy)-1,3-butadienes with dimethyl allene-1,3-dicarboxylate
-
The reaction of 1,3-bis(trimethylsiloxy)-1,3-butadienes with dimethyl allene-1,3-dicarboxylate provides a convenient and regioselective approach to a variety of functionalized 4-hydroxy- and 2,4-dihydroxy-homophthalates.
