Traceless stereoinduction in the one-pot assembly of all three rings of hexahydrodibenzopyrans

A one-pot method has been developed for the synthesis of all three rings of the hexahydrodibenzopyran ring system. This process involves a tandem sequence consisting of a benzannulation reaction of an alkenyl Fischer carbene complex and an alkyne followed by an elimination reaction that generates an o-quinone methide chromium tricarbonyl complex that is finally followed by an intramolecular heteroatom Diels-Alder cycloaddition. The stereoinduction for the overall process begins with the transfer of stereochemical information from the chiral center at the propargylic ether in the alkyne to the planar center of chirality in the in situ generated arene chromium tricarbonyl complexed intermediate and finally, after base-induced elimination to generate an o-quinone methide chromium tricarbonyl complexed intermediate, a transfer of chirality from the planar center of chirality in the o-quinone methide complex to the two new centers of chirality at positions 6a and 10a in the hexahydrodibenzopyran products upon intramolecular Diels-Alder reaction. The reactions of diastereomeric chiral propargyl ethers that contain an additional center of chirality can lead to high diastereoselectivity in the matched case and to low selectivity in the mismatched case.

Non-cryogenic metalation of aryl bromides bearing proton donating groups: Formation of a stable magnesio-intermediate

Bromine-metal exchange of o-bromobenzoic acid (1) with Bu2Mg followed by n-BuLi was successfully carried out at non-cryogenic temperature (>-20C), and gave a stabilized metal species which smoothly reacted with several electrophiles. This methodology expanded to several other bromides bearing proton donating groups (PDGs).

Controllable Synthesis of Mesoporous Iron Oxide Nanoparticle Assemblies for Chemoselective Catalytic Reduction of Nitroarenes

Iron(III) oxide is a low-cost material with applications ranging from electronics to magnetism, and catalysis. Recent efforts have targeted new nanostructured forms of Fe2O3 with high surface area-to-volume ratio and large pore volume. Herein, the synthesis of 3D mesoporous networks consisting of 4-5 nm gamma-Fe2O3 nanoparticles by a polymer-assisted aggregating self-assembly method is reported. Iron oxide assemblies obtained from the hybrid networks after heat treatment have an open-pore structure with high surface area (up to 167 m2 g-1) and uniform pores (ca. 6.3 nm). The constituent iron oxide nanocrystals can undergo controllable phase transition from gamma-Fe2O3 to alpha-Fe2O3 and to Fe3O4 under different annealing conditions while maintaining the 3D structure and open porosity. These new ensemble structures exhibit high catalytic activity and stability for the selective reduction of aryl and alkyl nitro compounds to the corresponding aryl amines and oximes, even in large-scale synthesis.

Vacuum co-pyrolysis of Chinese fir sawdust and waste printed circuit boards. Part I: Influence of mass ratio of reactants

Vacuum co-pyrolysis of Chinese fir sawdust (CFS) and waste printed circuit boards (WPCBs) at different mass ratios were examined in this paper. The structures and contents of the pyrolysis oils were analyzed by Fourier transform infrared (FTIR) spectroscopy and gas chromatography?mass spectrometry (GC?MS). The results showed that co-pyrolysis processes presented antagonistic effect in the yield of the total volatiles (liquid plus gas) at the experimental conditions, but it is beneficial to the formation of brominated aromatic compounds (whose total content in WPCBs pyrolysis oil was only 6.51?wt%, while in co-pyrolysis processes (CFS/WPCBs?=?4:1, 1:1, 1:4), they were 10.96?wt%, 7.98?wt% and 14.84?wt%, respectively). The co-pyrolysis processes were also analyzed by thermogravimetric (TG) analysis with evolved product analysis by FTIR. The results showed that the volatiles were mainly formed between 300 and 450?C, and after 450?C, there were mainly some noncondensable gases (CO2, CO and CH4) formed.

Novel tacrine?benzofuran hybrids as potential multi-target drug candidates for the treatment of Alzheimer?s Disease

Pursuing the widespread interest on multi-target drugs to combat Alzheimer?s disease (AD), a new series of hybrids was designed and developed based on the repositioning of the well-known acetylcholinesterase (AChE) inhibitor, tacrine (TAC), by its coupling to benzofuran (BF) derivatives. The BF framework aims to endow the conjugate molecules with ability for inhibition of AChE (bimodal way) and of amyloid-beta peptide aggregation, besides providing metal (Fe, Cu) chelating ability and concomitant extra anti-oxidant activity, for the hybrids with hydroxyl substitution. The new TAC-BF conjugates showed very good activity for AChE inhibition (sub-micromolar range) and good capacity for the inhibition of self- and Cu-mediated Abeta aggregation, with dependence on the linker size and substituent groups of each main moiety. Neuroprotective effects were also found for the compounds through viability assays of neuroblastoma cells, after Abeta1-42 induced toxicity. Structure-activity relationship analysis provides insights on the best structural parameters, to take in consideration for future studies in view of potential applications in AD therapy.

Discovery of (2S,3R)-N-[2-(pyridin-3-ylmethyl)-1-azabicyclo[2.2.2]oct-3-yl] benzo[b]furan-2-carboxamide (TC-5619), a selective alpha7 nicotinic acetylcholine receptor agonist, for the treatment of cognitive disorders

(2S,3R)-N-[2-(Pyridin-3-ylmethyl)-1-azabicyclo[2.2.2]oct-3-yl]benzo[b] furan-2-carboxamide (7a, TC-5619), a novel selective agonist of the alpha7 neuronal nicotinic acetylcholine receptor, has been identified as a promising drug candidate for the treatment of cognitive impairment associated with neurological disorders. 7a demonstrated more than a thousand-fold separation between the affinities for the alpha7 and alpha4beta2 receptor subtypes and had no detectable effects on muscle or ganglionic nicotinic receptor subtypes, indicating a marked selectivity for the central nervous system over the peripheral nervous system. Results obtained from homology modeling and docking explain the observed selectivity. 7a had positive effects across cognitive, positive, and negative symptoms of schizophrenia in animal models and was additive or synergistic with the antipsychotic clozapine. Compound 7a, as an augmentation therapy to the standard treatment with antipsychotics, demonstrated encouraging results on measures of negative symptoms and cognitive dysfunction in schizophrenia and was well tolerated in a phase II clinical proof of concept trial in patients with schizophrenia.

One-pot cascade synthesis of 2,3-disubstituted 2,3-dihydrobenzofurans via ortho-quinone methide intermediates generated in situ

A simple and efficient one-pot cascade reaction for the regioselective synthesis of trans or cis/trans 2,3-disubstituted 2,3-dihydrobenzofurans is reported. The method involves fluoride-induced desilylation, generation of o-quinone methide (o-QM) by chloride or nitrate anion elimination, Michael addition and intramolecular 5-exo-tet elimination of a bromide anion. Nitrate, acetoxy and chloride anions are compared as leaving groups in the formation of the in situ generated o-QM.

Synthesis and antibacterial activity of novel chalcone derivatives of apocynin

A series of novel chalcones 1a- 1l (12 compounds) has been synthesized by using commercially available apocynin and aromatic aldehydes. The newly synthesized chalcone derivatives were screened for their antibacterial activities against gram positive and gram negative bacteria at the concentrations 10 of mug/mL with reference to the standard antibacterial drug Gentamycin. The screening results revealed that among the tested analogs, compounds having the hetero rings such as benzo[b]furan, furan and pyridine (1j,1k and 1l) in the structure exhibited excellent antibacterial activity while the compounds bearing fluorine, 2-CF3, 4-CF3 and 4-OCF3 (1f, 1g, 1h and 1i) also exhibited good to excellent activity. 2013 Bentham Science Publishers.
