{{Expand German|Asterane|date=March 2026}} '''Asteranes''' are members of a series of cage hydrocarbons consisting of two cycloalkane rings linked to each other by methylene groups. Each linking face is thus a cyclohexane, which has a boat conformation.<ref>Henning Hopf, Classics in Hydrocarbon Chemistry, Wiley-VCH, New York, 2000, pages 34-37, {{ISBN|978-3-527-29606-4}}.</ref> They can be considered as homologues of the prismanes, but with a carbon linker between the faces rather than direct bonding. The molecules having linear, triangular, and square bases, [2]asterane (also known as diasterane),<ref>{{cite journal |last1=Otterbach |first1=Andreas |last2=Musso |first2=Hans |title=Diasterane (Tricyclo[3.1.1.1<sup>2,4</sup>]octane) |journal=Angewandte Chemie International Edition in English |date=June 1987 |volume=26 |issue=6 |pages=554–555 |doi=10.1002/anie.198705541}}</ref> [3]asterane, and [4]asterane, have been synthesized and studied experimentally, and many higher members of the series have been studied using computer models.
