IR and PMR spectroscopy and chemical methods have been used to establish the structures of stereoisomeric 1-(3-phenylprop-2-ynyl)-2-methyldecahydroquinol-4-ones and the corresponding acetylenic alcohols. In the PMR spectrum two quartets of protons are seen for C(/sub 3/) with /sup 3/JHH constants characteristic of the axial 2-H proton. Consequently, the methyl group is axially disposed. The signals for protons 9-H and 10-H fall within the resonance region of the C(/sub 3/) protons. Deuteration under keto-enol tautomeric conditions enabled the chemical shifts and the coupling constants of these protons to be measured.
