Abstract

Novel Dienes and Dienophiles. Part 8. Highly Functionalized, Angularly Anellated Aromatic Compounds from Dendralenes. -Cross-conjugated oligoenes [3]dendralene (I) or [4]dendralene (XI) undergo diene-transmissive Diels-Alder reactions with acetylenedicarboxylate (II) to give cycloadducts which are further elaborated to afford the desired polycycles (X) and (XIV). -(HOPF*, H.; YILDIZHAN, S.; Eur.
