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.

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.

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.

Application of 1552-42-7, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1552-42-7, Name is Crystal violet lactone,introducing its new discovery.

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.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1552-42-7, and how the biochemistry of the body works.Application of 1552-42-7

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.

Copper-Catalyzed Functionalizations of C60 with Amino Alcohols

CuI-catalyzed diverse functionalizations of C60 with amino alcohols with aerobic oxygen as the sole oxidant have been explored. For 2-/3-amino alcohols, an aminooxygenation reaction occurs to generate fulleromorpholine and fullerooxazepane derivatives. When a tethered furan ring exists, a further intramolecular [4 + 2] reaction with the neighboring double bond occurs to furnish the cis-1 products. In the case of 4-/5-amino alcohols, methanofullerenes linking with cyclic amides are obtained through cyclic enamine intermediates.
