Abou Elmaaty, Tarek; Elsisi, Hanan; Negm, Ilham published the artcile< Dyeing Characteristics of Polypropylene Fabric Dyed with Special Disperse Dyes Using Supercritical Carbon Dioxide>, Reference of 21667-62-9 , the main research area is polypropylene fabric dyeing disperse dye supercritical carbon dioxide.

Using disperse dyes of different colors and hues to produce a variety of shades is necessary for the industrialization of supercritical fluid dyeing of polypropylene. Eight derivatives of 3-(3-chlorophenyl)-1-phenyl-4-(diazenyl derivatives)-1H-pyrazol-5-amine dye were synthesized explicitly for use in supercritical carbon dioxide medium. Polypropylene dyeing was studied in supercritical carbon dioxide under varying conditions: Dyeing temperatures ranged from 100°C to 120°C, dying times ranged from 1 h to 2 h, concentrations ranged from 2% owf (on the weight of fabric) to 4%, and pressures ranged from 15 to 25 MPa. Significant improvement of the colorfastness to washing and rubbing was observed Raman spectroscopy was performed and showed conclusively that the dye was absorbed within all layers of polypropylene. This study achieved the elimination of water and its costly processing in the dyeing of synthetic fabrics.

Glover, Christian; Merritt, Eleanor A.; Bagley, Mark C. published the artcile< Synthesis of saramycetic acid>, Electric Literature of 6136-93-2, the main research area is saramycetic acid preparation degradation product thiopeptide antibiotic cyclothiazomycin.

The first reported synthesis of saramycetic acid [2′-acetyl-[2,4′-bithiazole]-4-carboxylic acid], a degradation product of the complex thiopeptide antibiotic cyclothiazomycin, is achieved in nine steps and 11% overall yield from diethoxyacetonitrile by a strategy which incorporates two Hantzsch thiazole syntheses using thioamides prepared from the corresponding nitriles without the use of gaseous H2S. The synthetic material was transformed to Me saramycetate, which had spectroscopic properties in excellent agreement with the literature data.

Lai, Nang Duy; Nguyen, Thu Trang; Nguyen, Nhu Ngan Ha; Retailleau, Pascal; Mac, Dinh Hung; Nguyen, Thanh Binh published the artcile< Direct access to 2-aryl-3-cyanothiophenes by a base-catalyzed one-pot two-step three-component reaction of chalcones with benzoylacetonitriles and elemental sulfur>, Related Products of 21667-62-9, the main research area is chalcone benzoylacetonitrile diazabicyclooctane catalyst Michael addition sulfuration cyclization; diaryl cyanothiophene preparation; benzoylacetate chalcone diazabicyclooctane catalyst Michael addition sulfuration cyclization; diarylthiophene carboxylate preparation.

Herein, unexpected results on the formation of 3-cyanothiophene derivatives as the major products via a three-component reaction of chalcones, benzoylacetonitriles and elemental sulfur along with the minor products 2-aminothiophenes was reported. The ratios between these two thiophene products is 4 : 3 and could be varied by simply changing the promoting base as well as its stoichiometric ratio. The method was successfully extended to benzoylacetate in place of benzoylacetonitrile to provide thiophene-3-carboxylates.

Zhou, Chao; Diao, Pinhui; Li, Xiaoji; Ge, Yanqin; Guo, Cheng published the artcile< Facile photochemical synthesis of α-ketoamides and quinoxalines from amines and benzoylacetonitrile under mild conditions>, COA of Formula: C9H6ClNO, the main research area is acyl acetonitrile amine photochem oxidative coupling reaction; ketoamide preparation; phenylenediamine acyl acetonitrile photochem cyclocondensation reaction; arylquinoxaline carbonitrile preparation.

A selective protocol for the synthesis of either α-ketoamides or quinoxaline derivatives under the same reaction conditions was achieved simply by varying substitution number of amino-groups. The method features metal-free, room temperature and broad substrate scope as well as no extra oxidant. This process applied to various substituent groups and provided products in moderate to good yield. Finally, a rational mechanism was proposed.

Tian, Shi-Kai; Hong, Ran; Deng, Li published the artcile< Catalytic Asymmetric Cyanosilylation of Ketones with Chiral Lewis Base>, SDS of cas: 6136-93-2, the main research area is ketone dialkoxy catalytic asym cyanosilylation chiral Lewis base; cyanohydrin silylated asym synthesis; cinchona alkaloid chiral catalyst enantioselective cyanosilylation dialkoxy ketone.

A highly enantioselective cyanosilylation of α,α-dialkoxy ketones R1COCH(OR2) (R1 = Me, Me2CH, n-Bu, Ph, 4-MeOC6H4, PhCH2, PhCH:CH, PhCC, etc.; R2 = Et, n-Pr) with trimethylsilyl cyanide catalyzed by modified cinchona alkaloids was developed. This reaction is the first highly enantioselective cyanosilylation of ketones catalyzed by an organic chiral Lewis base and, combined with the versatility of the acetal functionality, provides a broadly useful synthetic method for chiral building blocks bearing quaternary stereocenters. Acetal ketones, readily accessible but previously unexplored in asym. synthesis, demonstrate unusual reactivity and selectivity toward the nucleophilic cyanosilylation, thereby suggesting that they may be interesting substrates for other catalytic enantioselective reactions.

We have expanded our previously reported series of pyrazole-based inhibitors of the TGF-β type I receptor kinase domain (TβR-I) to now include new 5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole analogs. Limited examination of the SAR of this new series in both enzyme and cell based in vitro assays has revealed selectivity differences with respect to p38 MAP kinase (p38 MAPK) depending on the nature of the warhead’ group on the dihydropyrrolopyrazole ring. As with our original pyrazole series, Ph substituents tended to show greater selectivity against p38 MAPK than those comprised of the quinoline-4-yl moiety. We have also achieved co-crystallization and X-ray anal. of compounds I and II, two potent examples of this new series, with the TβR-I receptor kinase domain.

The preparation of an unprecedented series of nucleobase-modified 3-fluoro-2-(phosphonomethoxy)propyl (FPMP) acyclic nucleosides in both their (R) and (S) enantiomerically pure forms is described. The synthesis focused on a Mitsunobu alkylation reaction to construct the C-N(9) bond between a chiral fluorinated side-chain residue and 6- or 7-modified guanine analogs. Prodrugs of FPMP-7-deazaguanine were also synthesized by derivatization of the corresponding phosphonic acid functionality with (bis)diamyl aspartate amidate groups, leading to moderate activity against human immunodeficiency virus type 1 (HIV-1).
