## Abstract The NMR spectra of a number of 2,4βdisubstituted 1,3βdioxolanes have been recorded and the proton chemical shifts and coupling constants derived from complete spectral analysis. Vicinal coupling constants were found to be dependent on the substituent at Cβ4 and this effect is more prono
