Aminostyrylbenzofuran derivatives as potent inhibitors for Abeta fibril formation

The synthesis of a novel series of aminostyrylbenzofuran derivatives 1a-w and their inhibitory activities for Abeta fibril formation were described. All the synthesized compounds were evaluated by thioflavin T (ThT) assay and displayed potent inhibitory activities for Abeta fibril formation. Among them, compounds 1i and 1q exhibited excellent inhibitory activities (IC50 = 0.07 and 0.08 muM, respectively) than those of Curcumin (IC50 = 0.80 muM) and IMSB (IC50 = 8.00 muM) as reference compounds. Both compounds were selected as promising candidates for further biological evaluation.

Microcapsule encapsulated with leuco dye as a visual sensor for concrete damage indication: Via color variation

A microcapsule-type visualization sensor for concrete structural damage indication is proposed in this article. Crystal violet lactone, as damage indicator, was microencapsulated within poly(methyl methacrylate) to synthesize the sensor. The successful encapsulation was confirmed by Fourier transform infrared spectrometry. Microcapsules of different diameters and size distributions were obtained by varied stirring speeds. The fabricated microcapsules were embedded into a polymer coating to accomplish the damage indication. When cracks propagated in the coating, the crystal violet lactone in leuco form was released from the ruptured microcapsules. Due to reacting with silicon dioxide in concrete, the released crystal violet lactone turned blue and highlighted the damaged area. It was verified that the visualization performance of the sensor showed good durability in both dry and wet conditions. The proposed microcapsule-type visualization sensor has advantages of easy fabrication, high indication stability, and no special equipment requirements, which will reduce the complexity of concrete structural health monitoring significantly.

PROCESS FOR PREPARING 5-SUBSTITUTED -1-(4-FLUOROPHENYL) -1,3-DIHYDROISOBENZOFURANS

The present invention relates to a method for preparation and isolation of hitherto unknown solid boron complex of formula (v), which are obtained when 5-substituted phthalides are reacted with a solution of 4-fluorophenylmagnesiumbromide, followed by in situ reduction and complex formation in the presence of sodiumborohydride. Such boron complexes can be conveniently filtered to remove structurally similar impurities and subsequently subjected to cyclisation reaction in acidic medium to get high pure 5-substituted phthalens, which are key starting materials for manufacturing citalopram and pharmaceutically acceptable acid addition salts.

Synthesis of fused furans by gas-phase pyrolysis of 2-allyloxyaryl-propenoic esters

Flash vacuum pyrolysis of 2-allyloxypropenoic esters (e.g. 7) gives benzo[b]furans (e.g. 32) in synthetically useful yields by sequential generation of a phenoxyl radical, cyclisation and ejection of the carboxylic ester function as a free radical leaving group. The method is compatible with a range of substituents on either the benzene ring or the propenoate chain, and is particularly effective for 2-substituted benzo[b]furans. The natural products 5-methoxybenzo[b]furan 1 and angelicin 2 have been synthesised in three and four steps respectively from commercially available starting materials by this route. Related cyclisations to give naphtho[2,1-b]furan 40 were complicated by competitive formation of naphtho[2,1-b]pyran-3-ones (e.g. 41 and 42), but the yield of the required product could be optimised by the choice of the radical precursor. Annelation of a furan ring onto a thlophene is also possible by this method, but lower yields are obtained in such pyrolyses.

N-Arylation of heterocycles promoted by tetraethylenepentamine in water

Tetraethylenepentamine and triethylenetetramine are found to be efficient organic bases for the N-arylation of pyrazole and imidazole with aryl and heteroaryl-iodides and -bromides catalyzed by CuI in water at moderate temperature. The cross-couplings proceed smoothly with good to excellent yields and a variety of functional groups are tolerated under this condition.

Catalytic depolymerization of alkali lignin in subcritical water: Influence of formic acid and Pd/C catalyst on the yields of liquid monomeric aromatic products

Alkali lignin was subjected to depolymerization in subcritical water at 265 C, 6.5 MPa for reaction times between 1-6 h in a batch reactor and in the presence of formic acid (FA) and Pd/C catalyst. The oil products were extracted into diethyl ether and contained >90% of single-ring phenolic compounds. The reaction of lignin in subcritical water alone yielded 22.3 wt% oil containing 56% guaiacol as the main product. A maximum oil yield of 33.1 wt% was obtained when the lignin was reacted in the presence of formic acid alone. In the presence of FA, catechol became the predominant compound, with more than 80% of the ether extract after 6 h. The conversion of guaiacol to catechol in the presence of formic acid suggested the hydrolysis of O-CH3 ether bonds. In addition, the yields of alkyl guaiacols increased in the presence of FA. The use of 5 wt% Pd/C catalyst with FA slightly decreased the yields of oil products but led to compounds indicative of hydrogenolysis of aryl-O ether bonds as well as hydrogenation of CC bonds.

First measurements of absolute rate constants for oxacarbene intermediates produced in the photochemistry of benzocyclobutenedione

The photochemistry of benzocyclobutenedione in solution has been examined by use of laser flash photolysis techniques. Two rapid processes appear to compete. One leads to the formation of the long-lived bisketene IV, which can be readily observed (lambdamax 380 nm). The other process leads to oxacarbene III. This carbene could not be monitored directly, but probing techniques, with pyridine and adamantanethione as probes, lead to readily detectable ylides that can be employed to characterize the kinetic behavior of III. Thus, III lives about 20 mus in toluene and can be trapped by typical carbene scavengers such as alcohols. Carbene trapping by alcohols is in fact a complex reaction, since it also leads to equilibration with a short-lived intermediate (studied in detail in methanol/acetonitrile) that in turn can be trapped by alcohols, azides, and halides. This intermediate is tentatively assigned to carbocation VIII formed by solvent protonation of III.
