The stereochemistry of some diacetals of o ‐phthaldialdehyde with 2‐substituted‐1,3‐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.
