Synthesis and catalytic activity of ruthenium indenylidene complexes bearing unsymmetrical NHC containing a heteroaromatic moiety

New robust and air stable ruthenium(ii) indenylidene second generation olefin metathesis catalysts with unsymmetrical N-heterocyclic carbene (NHC) ligands were synthesized. Model metathesis reactions were performed in the presence of newly-developed complexes in commercial grade toluene under air, leading to high conversions and good selectivities.

Palladium-catalyzed decarboxylative C-H bond arylation of thiophenes

An efficient method involving a Pd/PCy3 catalyst in combination with a stoichiometric amount of Ag2CO3 has been established for the decarboxylative C-H bond arylation of thiophenes to give 2-arylthiophenes (see scheme; Cy=cyclohexyl). Electron-rich, electron-deficient, and heterocyclic benzoic acids can be used as the arylating reagent and a broad range of substituents on the thiophene are tolerated.

Aromatic Spiranes, XVI: Syntheses of Mono- and Dianellated 2,2′-Spirobiindane-1,1’diones

The spiroketones 19, 21, 24, 27, and 31 were prepared by cyclisation of the dicarboxylic acids and their acid chlorides, resp., (18, 20, 22, 23, 25, 26, 28, and 30) with polyphosphoric acid (PPA) or SnCl4.The latter compounds were synthesized by alkylation of the appropriate beta-keto esters 10, 11, 12, and 13 with the “benzyl chlorides” 14, 15, 16, and subsequent retro-Claisen reaction.The spiro compounds 21a and 39 were obtained by PPA-cyclisation of the keto acids 35 and 38, which in turn were prepared by aldol-reaction of the ketones s-hydrindacen-1-on and 9a with phthalaldehydic acid to the olefinic keto acids 33 and 36 followed by catalytic hydrogenation. – Keywords: Indane-1-one; s-Hydrindacene-1-one; Tetrahydrobenzoindane-1-one; beta-Keto esters; Phthalaldehydic acid; Spiro cyclisation; 2,2′-Spirobiindane-1,1′-diones; 1H-nmr spectra; Mass spectra

Effect of cell therapy with allogeneic osteoblasts on bone repair of rat calvaria defects

Background aims: Regenerative medicine strategies based on cell therapy are considered a promising approach to repair bone defects. The aims of this study were to evaluate the effect of subculturing on the osteogenic potential of osteoblasts derived from newborn rat calvaria and the effect of these osteoblasts on bone repair of rat calvaria defects. Methods: Cells were obtained from 50 newborn rat calvaria, and primary osteoblasts (OB) were compared with first passage (OB-P1) in terms of osteogenic potential by assaying cell proliferation, alkaline phosphatase (ALP) activity, extracellular matrix mineralization and gene expression of the osteoblastic markers RUNX2, ALP, osteocalcin and bone sialoprotein. Then, 5-mm calvaria defects were created in 24 Wistar rats, and after 2 weeks, they were locally injected with 50 muL of phosphate-buffered saline containing either 5 ¡Á 106 osteoblasts (OB-P1, n = 12) or no cells (control, n = 12). Four weeks post-injection, the bone formation was evaluated by micro-computed tomography and histological analyses. Data were compared by analysis of variance, followed by the Student-Newman-Keuls’s test or Student’s t-test (P ? 0.05). Results: OB-P1 showed high proliferation and ALP activity, and despite the reduced gene expression of osteoblastic markers and extracellular matrix mineralization compared with OB, they displayed osteogenic potential, being a good choice for injection into calvaria defects. The micro-tomographic and histological data showed that defects treated with OB-P1 presented higher bone formation compared with control defects. Discussion: Our results indicate that cells derived from newborn rat calvaria retain osteoblastic characteristics after subculturing and that these osteoblasts stimulate bone repair in a rat calvaria defect model.

Transition metal free hydrolysis/cyclization strategy in a single pot: Synthesis of fused furo N-heterocycles of pharmacological interest

A transition metal free tandem two-step strategy has been developed involving hydrolysis of 2-chloro-3-alkynyl quinoxalines/pyrazines followed by in situ cyclization of the corresponding 2-hydroxy-3-alkynyl intermediates in a single pot leading to fused furo N-heterocycles as potential inhibitors of sirtuins. A representative compound showed promising pharmacological properties in vitro and in vivo.
