NMR spectral studies of dimedone- aldehyde adducts Part 2. ~1H and ~(13)C NMR studies of the adducts

摘要

A detailed study of the 270 MHz ~1H and 67 MHz ~(13)C NMR spectra of four series of dimedone adducts and "anhydrides" is presented. A valuable ~5J_(HH) homoallylic coupling has been identified which has facilitated signal locations utilising 2D HETCORand COLOC experiments. Some earlier spectral assignments are revised.
