The scope and limitations of Eaton's rhodium(I)-catalyzed valence isomerization of cubane to cyclooctatetraene (COT) were investigated in the context of functional group tolerability, multiple substitution modes and the ability of cubane-alcohols to undergo one-pot tandem Ley–Griffith Wittig reactions in the absence of a transition metal catalyst.

Despite the difficulty in administering a safe dose regimen and reports of emerging resistance, warfarin (1) remains the most widely-used oral anticoagulant for the prevention and treatment of thrombosis in humans globally. Systematic substitution of the warfarin phenyl ring with either 1,3,5,7-cyclooctatetraene (COT) (2), cubane (3), cyclohexane (4) or cyclooctane (5) and subsequent evaluation against the target enzyme, vitamin K epoxide reductase (VKOR), facilitated interrogation of both steric and electronic properties of the phenyl pharmacophore. The tolerance of VKOR to further functional group modification (carboxylate 14, PTAD adduct 15) was also investigated. The results demonstrate the importance of both annulene conferred π-interactions and ring size in the activity of warfarin.

A collection of novel, pharmaceutically relevant cubane-containing molecules has been prepared from the commercially available cubane-1,4- dimethylester. A range of synthetic methods have been applied to prepare these cubane building blocks with one or two functional handles to allow easy incorporation into existing medicinal chemistry programs.
Hyperconjugation involving strained carbon-carbon bonds. Application of the variable oxygen probe to ester and ether derivatives of cubylmethanol

Application of the variable oxygen probe to derivatives of (4-methoxycarbonyl)cubylmethanol 11 demonstrated a strong response of C-OR bond distance to the electron demand of the OR substituent, consistent with an enhanced σ-donor ability of the strained C-C bonds of cubane. The extent of cubane donor ability was found to be superior to an unstrained donor 13, comparing data extracted from the Cambridge Structural Database (T. W. Cole, Ph.D. Dissertation, University of Chicago, 1966), but weaker than the previously studied cyclopropane donors. Structural evidence is also found for σCC-π*CO interactions in these structures.

Synthesis and preliminary evaluation of (S)-2-(4'-carboxycubyl)glycine, a new selective mGluR1 antagonist

The synthesis and the pharmacological evaluation at metabotropic glutamate receptors of S-2-(4'-carboxy-cubyl)glycine (ACUDA, 9) are described. S-2-(4'-Carboxy-cubyl)glycine is a structurally novel group I selective antagonist for mGluR1 subtype.
