The (13)C-n.m.r. spectra of a range of isopropylidene acetals of carbohydrates have been studied.Attention has focused on the chemical shifts of the acetals carbon and methyl groups of the acetals.These parameters are characteristic of ring-size (1,3-dioxolane, and 1,3-dioxepane) and can sometimes give further information on ring-fusions and conformations.An example is given of the application of the method to 1,3:2,4:5,6-tri-O-isopropylidene-D-glucitol.
