Cycloadditions of 1,4-Bis-Trimethyl-siloxy-1,3-cyclohexadiene

Abstract

The cycloaddition reactions of 1,4-bis-trimethylsiloxy-1,3-cyclohexadiene with maleic anhydride, dimethyl acetylenedicarboxylate, diethylfumarate and methyl acrylate have been studied. The moderate to good yields obtained in these reactions indicate that this diene will be useful in the synthesis of 1,4-bis-oxygenated bicyclo[2.2.2]-octanes.
