Abstract

Permethylated 1, 3, 5-tri-and 1, 3, 5, 7-tetracarbonyl compounds were prepared and structurally characterized. 2, 2, 4, 4-Tetramethyl-3, 5-dioxoesters were prepared by condensation of 1, 3-bis (trimethylsilyloxy)-1, 3-butadienes with acid chlorides and subsequent reaction with methyl iodide. 2, 2, 4, 4, 6, 6-Hexa-substituted 3, 5-dioxopimelates were prepared by condensation of 1, 3-bis (trimethylsilyloxy)-1, 3-butadienes with methyl ...
