The 1 H– 13 C NMR shifts as well as 1 H and 13 C coupling constants of 14 alkoxymethylene malonic acid and acetoacetic acid derivatives and two alkoxymethylene acetylacetones are reported. The 17 O NMR spectra have been recorded for six of them. The long‐range coupling 3 J (HCCC R ) has been used for determining the stereochemistry of the double bond.
