In this work, the direct C-H functionalization reaction of 1,4-dimethoxybenzene with N-hydroxyphthalimide has been disclosed. A previously unknown product C-O coupling and was obtained. The proceeded under mild conditions, in which a commercially available manganese-based oxidizing agent used for generation phthalimide-N-oxyl radical. obtained compound is promising valuable precursor O-aryl hyd...

in this work, so3h-functionalizedphthalimide (sfp) as a so3h-containing solid acid is prepared by the reaction of phthalimide with chlorosulfonic acid, and characterized by ft-ir, 1h and 13c nmr, mass, tg, dtg, xrd and sem. then, it is utilized as a highly efficient, heterogeneous and green catalyst for the one-pot multi-component condensation of dimedone with arylaldehydes, β-ketoesters and am...

Four new macrocyclic-phthalimide ligands were synthesised via the coupling of N-(3-bromopropyl)phthalimide either to cyclen (1,4,7,10-tetraazacyclododecane) itself or its carboxylate-functionalized analogues, and photophysical studies were carried out on their corresponding Tb(III) complexes in aqueous media as a function of pH. Luminescence intensities of Tb·L1a–Tb·L3a were in ‘switched off’ m...

We report a panel of carboxylates and sulfonamides incorporating phthalic anhydride and phthalimide moieties in their structure and their interaction with the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1). They were synthesized from substituted anthranilic acids and trimellitic anhydride chloride, followed by reaction with primary amines and were tested for the inhibition of five physiologi...

The title compound, C(19)H(19)NO(10), was obtained from the reaction of α-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hy-droxy-phthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent mol-ecules, in which the O-CH-O-N torsion angles are 73.0 (4) and 65.0 (4)°. The hexa-pyranosyl rings adopt chair conformations and the substituent groups are in equatorial po...
