Structure-property relationships and nonlinear optical effects in donor-substituted dicyanopyrazine-derived push-pull chromophores with enlarged and varied π-linkers

Thirteen new, stable, push-pull systems featuring dimethylamino and pyrazine-2,3-dicarbonitrile moieties as the donor and acceptor, respectively, and systematically extended and varied π-linkers were prepared and investigated. Evaluation of the measured UV/Vis spectra, electrochemical data (cyclic voltammetry, rotating disc voltammetry, and polarography), X-ray data, and experimentally determined and calculated hyperpolarizability values enabled structure-property studies; these revealed some important structural features that affected the efficiency of intramolecular charge-transfer and nonlinear optical properties in this class ofheterocyclic push-pull chromophores. The charge-transfer transition was most significantly affected by structuralfeatures such as π-linker length, chromophore planarity, and the number of 1,4-phenylene/ethynylene subunits in the π-linker. Linear and nonlinear optical properties of push-pull chromophores featuring a pyrazine-2,3- dicarbonitrile acceptor moiety and dimethylamino donors were modulated by systematic extension and variation of the π-linker. The length and character of the π-linker used significantly influenced the efficiency of the donor-acceptor conjugation and nonlinear responses. Copyright

1-Benzhydryl-3-phenylurea and 1-benzhydryl-3-phenylthiourea derivatives: New templates among the CB1 cannabinoid receptor inverse agonists

New 1-benzhydryl-3-phenylurea derivatives and their 1-benzhydryl-3- phenylthiourea isosteres were synthesized and evaluated for their human CB 1 and CB2 cannabinoid receptor affinity. These compounds proved to be selective CB1 cannabinoid receptor ligands, acting as inverse agonists in a [35S]-GTPγS assay. The affinity of 3,5,5′-triphenylimidazolidine-2,4-dione and 3,5,5′-triphenyl-2- thioxoimidazolidin-4-one derivatives, possessing the 1-benzhydryl-3-phenylurea and 1-benzhydryl-3-phenylthiourea moiety, respectively, was also evaluated. In conclusion, the 1-benzhydryl-3-phenylurea scaffold seems to be a new interesting template of CB1 cannabinoid receptor inverse agonists.

Samarium diiodide promoted formation of 1,2-diketones and 1-acylamido-2-substituted benzimidazoles from N-acylbenzotriazoles

N-Acylbenzotriazoles, when treated with samarium diiodide in THF, undergo self-coupling reaction to afford 1,2-diketones in good to excellent yields; while when treated with samarium diiodide in CH3CN, they undergo ring-opening reaction to afford 1-acylamido-2-alkyl (or aryl) benzimidazoles in reasonable to good yields. A plausible mechanism was suggested.
