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