The synergistic effect of zinc and copper in Cu2O/ZnO nanoflake as a heterogeneous catalyst for the N-arylation of heterocycles with aryl halides and arylboronic acids in the absence of additional ligand in air were demonstrated. The catalyst was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), BET surface area measurement, and FT-IR spectroscopy.

Various representative copper(I)-exchanged zeolites were investigated for their catalytic potential in Chan-Lam cross-coupling reactions. CuI-USY appeared as the best catalyst and proved to efficiently promote C-N cross-coupling processes under attractive, simple, and practical conditions, namely refluxing in methanol under air and without any base.
N-(1-Oxy-2-picolyl)oxalamic acids as a new type of O,O-ligands for the Cu-catalyzed N-arylation of azoles with aryl halides in water or organic solvent

, p. 4101 - 4114 (2015/03/30)
N-(1-Oxy-pyridin-2-ylmethyl)oxalamic acids (L3-L5) were identified as novel efficient ligands for copper-catalyzed C-N cross-coupling of azoles and aryl halides in water. The N-arylation of imidazoles, indoles and pyrazoles proceeded with moderate to excellent yields and complete selectivity over aromatic amines and phenols. Moreover, L5, which is also efficient in organic solvent with low catalyst loading, can be used to promote the N-arylation reactions with water-sensitive materials. The catalytic mechanism was proposed based on the results of several verification experiments which indicated that the ligands as new-type chelators may coordinate to Cu(i) with two oxygen atoms of N-oxide and amide in the coupling process.

Methods of treating chronic arthritis and osteoporosis which utilize both known and novel compounds which would fall under the general formula:(HO)p--A--[--OS(O) 2 NR 1 R 2 ] zwherein A encompasses a wide range of values including but not limited to aryl, loweralkyl, cycloalkyl, and carbohydrates including sucrose and fructose; p is equal to the number of unreacted hydroxy groups contained on the molecule and may be zero; z is the number of --OS(O) 2 NR 1 R 2 groups and is always at least one; R 1 and R 2 are selected from hydrogen, loweralkyl, carboxy and the like; a novel process for preparing the compounds is provided wherein an appropriate sulfamic acid aryl ester is reacted with a hydroxy substituted A radical which may or may not contain thereon protected carboxyl, amino or hydroxy substituents, in an aprotic solvent containing a tertiary amine base. Pharmaceutical compositions for the treatment of chronic arthritis and osteoporosis are also provided.

Several imidazolylphenyl sulfamate and (imidazolylphenoxy)alkyl sulfamate derivatives were synthesized and evaluated as topically active carbonic anhydrase inhibitors. Water solubility, pKa, carbonic anhydrase inhibition, and partition coefficient for the compounds were measured. Sulfamic acid 2-ethyl ester monohydrochloride (16) has the best combination of properties and showed excellent topical activity in lowering the intraocular pressure in New Zealand white rabbits.
