This work reports a facial way to synthesize of an efficient catalyst based Ni–Pd alloy nanoparticles which supported on a new bio-inspired hierarchical porous silica and its catalytic activity in the one-pot Suzuki–Miyaura cross coupling-nitro reduction. The synthesized catalyst was fully characterized by FT-IR, XRD, FESEM–EDX, elemental mapping, TEM, ICP-AES, N2 adsorption–desorption, DRS–UV–Vis and XPS techniques. Use of inexpensive catalyst, high yields of the products and reusability of the catalyst are some of the advantages of our procedure. Graphical Abstract: [Figure not available: see fulltext.].

This report demonstrates that changing the position of the carbon-metal bond in a polypyridyl cyclopalladated complex, i.e. going from PdL1 (N^N^C^N) to PdL2 (N^N^N^C), dramatically influences the photodynamic properties of the compl

Xu, Lin-Lin,Wang, Xing,Ma, Biao,Yin, Ming-Xing,Lin, Hai-Xia,Dai, Hui-Xiong,Yu, Jin-Quan
, p. 5160 - 5164 (2018/06/21)
Here we report an efficient Cu(i)-mediated C-H amination reaction with oximes as amino donors to introduce NH2 groups directly. Various strongly coordinating heterocycles including quinoline, pyrimidine, pyrazine, pyrazole and triazole were tolerated well. The potential utility was further demonstrated in a late-stage modification of telmisartan (an antagonist for the angiotensin II receptor).
Novel Diarylurea Based Allosteric Modulators of the Cannabinoid CB1 Receptor: Evaluation of Importance of 6-Pyrrolidinylpyridinyl Substitution

Allosteric modulators of the cannabinoid CB1 receptor have recently been reported as an alternative approach to modulate the CB1 receptor for therapeutic benefits. In this study, we report the design and synthesis of a series of diarylureas derived from PSNCBAM-1 (2). Similar to 2, these diarylureas dose-dependently inhibited CP55,940-induced intracellular calcium mobilization and [35S]GTP-γ-S binding while enhancing [3H]CP55,940 binding to the CB1 receptor. Structure-activity relationship studies revealed that the pyridinyl ring of 2 could be replaced by other aromatic rings and the pyrrolidinyl ring is not required for CB1 allosteric modulation. 34 (RTICBM-74) had similar potencies as 2 in all in vitro assays but showed significantly improved metabolic stability to rat liver microsomes. More importantly, 34 was more effective than 2 in attenuating the reinstatement of extinguished cocaine-seeking behavior in rats, demonstrating the potential of this diarylurea series as promising candidates for the development of relapse treatment of cocaine addiction.
Meta-Selective CAr-H Nitration of Arenes through a Ru3(CO)12-Catalyzed Ortho-Metalation Strategy

The first example of transition metal-catalyzed meta-selective CAr-H nitration of arenes is described. With the use of Ru3(CO)12 as the catalyst and Cu(NO3)2·3H2O as the nitro source, a wide spectrum of arenes bearing diversified N-heterocycles or oximido as the directing groups were nitrated with meta-selectivity exclusively. Mechanism studies have demonstrated the formation of a new 18e-octahedral ruthenium species as a key ortho-CAr-H metalated intermediate, which may be responsible for the subsequent meta-selective electrophilic aromatic substitution (SEAr). Moreover, this approach provides a fast-track strategy for atom/step economical synthesis of many useful pharmaceutical molecules.
