Popis: A study of the 1 H and 13 C NMR spectra of adducts arising from the condensation of o -phthalaldehyde with an amide or a sulfonamide established the stereochemistry and differentiated between phthalan and isoindoline products for this reaction. The steric properties of the 2,6-dichlorobenzamide adduct appear to influence the vicinal H, OH coupling constant associated with the isoindoline ring.
