We wish to report the synthesis of tricyclo[3.3.0.03'7 ]octane (I) by a structurally unambiguous route and to describe the ring expansion of the derived carbinols II and III. Hydrocarbon I, for which we suggest the trivial name %isnoradamantane", may be regarded as a lower homolog of adamantane (IV)
The structure of the strained tricyclic hydrocarbon tricyclo [ 4.2.0.0'~~ I octane was determined by a combination of 1D and 2D NMR involving both proton and carbon signals. The stereochemistry of the molecule was determined by NOE difference spectroscopy. The assigned structure corresponds to the t
