There are many reports in the literature concerning /sup 1/H- and /sup 13/C-NMR investigations of the electronic and three-dimensional structures of cyclic acetals of aliphatic and aromatic aldehydes. In the present paper they report the results of their study of the structures of cyclic orthoesters and their analogs; highly characteristic signals of particular functional groups have been identified, thus enabling them to assign compounds to distinct homologous series based on this type of data. The shielding constants of the axial and equatorial protons attached to C/sup 4/ and C/sup 6/ are characteristic of the /sup 1/H-NMR spectra of 2-alkoxy-1,3-dioxanes.
