We have developed a high-efficiency and practical Cu-catalyzed cross-coupling to directly construct versatile α-aryl-esters by utilizing readily available aryl bromides (or chlorides) and malonates. These gram-scale approaches occur with turnovers of up to 1560 and are smoothly conducted by the usage of a low catalyst loading, a new available ligand, and a green solvent. A variety of functional groups are tolerated, and the application occurs with α-aryl-esters to access nonsteroidal anti-inflammatory drugs (NSAIDs) on the gram scale.

The intense research work in the field of medicinal chemistry has enhanced the significance of Biphenyl moiety as pharmacologically important compound. Some of the compounds bearing Biphenyl moiety possess important medicinal properties like antihypertensive and calcium channel blocker, anti-inflammatory, diuretic, anti-diabetic activity, antipsychotic and anxiolytic activity. The present article describes the synthesis of novel benzohydrazides and 2-phenylacetohydrazides bearing Biphenyl moiety and vanillin hybrid. The synthesized compounds (31-40) were characterized by 1H NMR, Mass and IR spectroscopic techniques and were evaluated for anti-inflammatory activity by carrageenan paw edema method. The results of the study revealed that compounds 39 and 40 (bearing 2-(4-nitrophenyl)acetohydrazide and 2-(2,3-dihydrobenzofuran-5-yl)acetohydrazide) showed maximum anti-inflammatory activity while the compounds 31, 32, 33, 34 and 38 bearing benzohydrazides displayed moderate anti-inflammatory activity.

Transition-metal-free synthesis of α-aryl esters and nitriles using arylboronic acids with α-aminoesters and α-aminoacetonitriles, respectively, as the starting materials has been developed. The reaction represents a rare case of converting C(sp3)-N bonds into C(sp3)-C(sp2) bonds. The reaction conditions are mild, demonstrate good functional-group tolerance, and can be scaled up. Touch base: A transition-metal-free protocol for the synthesis of α-aryl esters and nitriles by deaminative coupling is presented. Strong bases and transition-metal catalysts are not needed. The new synthetic method uses readily available starting materials and demonstrates wide substrate scope.
