Twenty-seven years ago, H. Hopf published the only previous comprehensive review on branched oligoenes that had the title "Dendralenes: A Neglected Family of Hydrocarbons". The dendralenes are no longer neglected. Research into the synthesis, properties, and applications of dendralenes is rapidly gaining momentum and this Review summarizes important recent findings. From significant fundamental properties (the first demonstration of alternating behavior since the annulenes) through to unparalleled complexity-generating synthetic transformations, this fundamental oligoene family is coming of age. Effective synthetic approaches to cyclic and acyclic dendralene systems are analyzed and classified. The most powerful synthetic transformations of the dendralenes, diene-transmissive Diels-Alder reactions, are surveyed in detail.
27 年前，H. Hopf 发表了唯一一篇关于支化寡烯的全面综述，题为“Dendralenes: A Neglected Family of Hydrocarbons”。如今，dendralenes 已不再被忽视。dendralenes 的合成、性质和应用研究正在迅速发展，本文综述了重要的最新发现。从显著的基本性质（自 annulenes 以来首次展示交替行为）到无与伦比的复杂性生成合成转化，这个基本的寡烯家族正在崭露头角。对环状和非环状 dendralene 系统的有效合成方法进行了分析和分类。对 dendralenes 的最强大的合成转化，即二烯传递的 Diels-Alder 反应，进行了详细的综述。
