Abstract
High-pressure Diels-Alder cycloaddition reactions of 5-ethenyl[2.2]indeno-paracyclophane ( 1 ) with 1,4-benzoquinone ( 2 ), N-phenylmaleimide ( 3 ), and 2-inden-1-one ( 4 ) have been studied. Attempts to convert the cycloadducts into the corresponding aromatic helicenophanes failed. All new compounds were characterized by extensive nuclear magnetic resonance (NMR) investigations.
