✦ Synopsis

In a recent communication (11, Schleyer and Aiskott pointed out that of the conceivable tricyclononanes only four (I-IV) do not possess three or four-membered rings or highly strained skeletons. Brendane (I), brexane (II) and noradamantane (III) are known (2). Be now wish to report the synthesis of the fourth member of this series, tricyclo[4.3.0.03'a1nonene (IV), colloquially termed "twist-brendane " (l), and to describe the unambiguous preparation of homoadamantsne (V) via a common intermediate.
