The total assignment of the 1 H and 13 C NMR spectra of 24 cis-endo and 15 cis-exo diastereoisomers of C-1-substituted 2,4-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one derivatives was deduced from the concerted application of DEPT, COSY, HETCOR, HMBC, HMQC and PS-NOESY experiments. The relative stereo
