Chemistry of 2,5-bis(trimethylsiloxy) furans. I: Preparation and diels-alder reactions

A number of substituted 2,5-bis (trimethylsioloxy) furans were prepared from the corresponding succinic anhydrides, and were found to be reactive dienes for the Diels-Alder reaction with electron - withdrawing dienophiles, giving p-quinones and hydroquinones.
