摘要：
The syntheses and thermal intramolecular Diels-Alder reactions of silyl acetal trienes possessing methyl groups at the allylic positions of the diene or dienophile are described. A model is proposed to account for the observed selectivities. The structures of the cycloadducts are unambiguously assigned by X-ray crystallographic analysis of derivatives.
