Abstract
A full structural and stereochemical assignment was achieved for sever al diastereoisomeric oxaspiro[4.4]nonane derivatives by the concerted use of modern gradient-based 1D and 2D experiments, The clean NOE data quickly obtained from high-quality GROESY spectra together with proto n and carbon chemical shift correlations afforded the main clue in suc h stereochemical elucidations.
