The acetolysis of 4-cyclooctenylmethyl toluene-p-sulphonate gives rise to bicyclo[4.2.1]non-2-ene, and bicyclo[3.3.1]non-2-ene. The chemistry of the epimeric bicyclo[3.3.1]nonan-2-ols is discussed.
An investigation of the internal enolate alkylation process as a route to bicyclo[3.3.1]nonanes has been made. Application of the method to 4-(3-hydroxylpropyl)cyclohexanone has been found to provide an economical synthesis for 2-bicyclo[3.3.1]nonanone.

The preparation and configurational assignments of the epimeric 3-carboxybicyclo[3,3,1]nonanes are described, and the free energy difference between their methyl esters is measured. The bromination products of bicyclononan-2-one are discussed, and the deamination of a boat cyclohexylamine is reported.
