Layered Compounds. XXXIV. Molecular and Crystal Structure of a Polycyclic Compound from Novel Cycloaddition Reaction of Triple-layered Anthracenophane

An unusual Diels-Alder reaction was observed to give intramolecular cycloadducts during the syntheses of triple-layered cyclophanes containing anthracene nucleus. The structure of the product was determined by spectral and X-ray crystal analyses. The crystal is monoclinic, P21/c, with a=15.896, b=8....

Summary:An unusual Diels-Alder reaction was observed to give intramolecular cycloadducts during the syntheses of triple-layered cyclophanes containing anthracene nucleus. The structure of the product was determined by spectral and X-ray crystal analyses. The crystal is monoclinic, P21/c, with a=15.896, b=8.937, c=18.575 Å, β=120.31°, Z=4. The crystal structure was determined by the direct method using the MULTAN program and refined by the block-diagonal least-squares method to an R index of 0.081. The structure of the molecule is fairly strained.
