✦ Synopsis

analysis / NMR spectra I Solid-state structure / 1,3-Dioxane derivatives of o-phthaldialdehyde / Chromatographic separation of cis,trans isomers The stereochemistry of some diacetals of o-phthaldialdehyde with 2-substituted-l,3-propanediols was studied using NMR spectroscopy and the solid-state molecular structure of one compound established by single-crystal X-ray diffractometry.

The cis and trans isomers of some diacids and diesters, produced as derivatives bearing the desired substituents in the 5 and 5' positions of the heterocycles, have been separated by preparative TLC and identified by their NMR spectra.
