Notes:
The 13C NMR spectra of 24 1,3-dioxolane derivatives are reported in an attempt to propose parameters for the C-2, C-4 and C-5 shifts from the 2-Me and 4-Me substituents, based on the ring stereochemistry. These parameters are obtained from simultaneous equations, and clearly agree with those calculated by the use of pattern molecules. The calculated parameter for the C-4 shift due to a 2-Me group differs notably from that proposed by other workers.
