The relative axial–equatorial position ofspiro[4.5]decanes substituted in the 1,4‐positionsby oxygen or nitrogen were assigned by 15 N and 17 O NMR spectroscopy. The substituent, chemical exchange andsteric effects upon the chemical shifts are discussed. A linearrelationship between 15 N and 17 O was found andthe relative configuration of the chiral spiro atom was determined.Copyright © 1999 John Wiley & Sons. Ltd.
