Carbon‐13 NMR spectroscopy of kawa‐pyrones

Abstract

Abstract 13 C NMR spectra of six kawa‐pyrones (styryl α‐pyrones) have been assigned. The assignments are based on the splitting pattern in the coupled spectra, comparison of the chemical shifts with those of model compounds and by application of additivity relationships. The 13 C NMR of styrene was also reinvestigated.
