An improved process for the preparation of fluconazole is described. 1,3-Difluorobenzene underwent Friedel-Crafts acetylation with chloroacetyl chloride without solvent to give 2,4-difluorophenylacetyl chloride in 98% yield. This chloride was substituted with 1H-1,2,4-triazole in refluxing toluene in the presence of sodium bicarbonate, leading to 1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone in 71% yield. Finally, one-pot Corey-Chaykovsky reaction of the carbonyl with Me3SOI followed by ring-opening with 1H-1,2,4-triazole to afford fluconazole in 76% yield.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone(SMILESS: FC1=CC=C(C(CN2N=CN=C2)=O)C(F)=C1,cas:86404-63-9) is researched.Related Products of 1762-34-1. The article 《Process Development of Voriconazole: A Novel Broad-Spectrum Triazole Antifungal Agent》 in relation to this compound, is published in Organic Process Research & Development. Let’s take a look at the latest research on this compound (cas:86404-63-9).

In the synthesis of (2R,3S)-2-(2,4-difluorophenyl)-3-(5-fluoro-4-pyrimidinyl)-1-(1H-1,2,4-triazol-1-yl)-2-butanol (voriconazole), the relative stereochem. is set in the addition of a 4-(1-metalloethyl)-5-fluoropyrimidine derivative to 1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)-1-ethanone. The diastereocontrol of this reaction has been examined by variation of pyrimidine substitution pattern and by changes in the metalation and reaction conditions. Excellent diastereoselection (12:1) is obtained using an organozinc derivative of 6-(1-bromoethyl)-4-chloro-5-fluoropyrimidine. After removal of the chlorine from the pyrimidine ring, the absolute stereochem. of voriconazole is established via a diastereomeric salt resolution process using (1R)-10-camphorsulfonic acid. Synthetic routes to the pyrimidine partner have also been evaluated. The initial six-step development route from 5-fluorouracil has been superseded by a four-step synthesis involving fluorination of Me 3-oxopentanoate and cyclization with formamidine acetate.

Author is Sheng, Chunquan; Wang, Wenya; Che, Xiaoying; Dong, Guoqiang; Wang, Shengzheng; Ji, Haitao; Miao, Zhenyuan; Yao, Jianzhong; Zhang, Wannian.

Lanosterol 14α-demethylase (CYP51) is an important target for antifungal drugs. An improved three-dimensional model of CYP51 from Candida albicans (CACYP51) was constructed by ligand-supported homol. modeling and mol. dynamics simulations. The accuracy of the constructed model was evaluated by its performance in a small-scale virtual screen. The results show that known CYP51 inhibitors were efficiently discriminated by the model, and it performed better than our previous CACYP51 model. The active site of CACYP51 was characterized by multiple copy simultaneous search (MCSS) calculations On the basis of the MCSS results, a series of novel azoles were designed and synthesized, and they showed good in vitro antifungal activity with a broad spectrum. The MIC80 value of four of these compounds against C. albicans is 0.001 μg mL-1, indicating that they are promising leads for the discovery of novel antifungal agents.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 86404-63-9, is researched, SMILESS is FC1=CC=C(C(CN2N=CN=C2)=O)C(F)=C1, Molecular C10H7F2N3OJournal, Article, Research Support, Non-U.S. Gov’t, European Journal of Medicinal Chemistry called Design, synthesis, and biological evaluation of novel triazole derivatives as inhibitors of cytochrome P450 14α-demethylase, Author is Chai, Xiaoyun; Zhang, Jun; Hu, Honggang; Yu, Shichong; Sun, Qingyan; Dan, Zhigang; Jiang, Yuanying; Wu, Qiuye, the main research direction is triazole preparation cytochrome P 450 14 alpha demethylase inhibitor; mol modeling triazole cytochrome P 450 14 alpha demethylase.Application In Synthesis of 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone.

Based on the results of computational docking to the active site of the cytochrome P 450 14α-demethylase (CYP51), a series of 1-(1H-1,2,4-triazole-1-yl)-2-(2,4-difluorophenyl)-3-substituted-2-propanols I (R = H, 2-F, 2,4-Cl2, 4-MeO2C, PhO2C, etc.) as analogs of fluconazole were designed, synthesized, and evaluated as antifungal agents. The MIC80 values indicate that compounds I (R = H, 2-F, 4-Me, etc.) exhibited higher activity against nearly all fungi tested except Aspergillus fumigatus than fluconazole, while I (R = COOR1, R1 = Me, Et, iso-Pr, COOAr, etc.; Ar = Ph, 3-O2NC6H4, 4-ClC6H4, 2-MeO2CC6H4, etc.) showed no activity or only moderate activity against all fungi tested. Noticeably, the MIC value of I (R = H, 2-F, 4-Cl) is 64 times lower than that of fluconazole against Microsporum gypseum in vitro. And I (R = H, 2-F, CO2Et) showed 128 times higher activity (with the MIC80 value of 0.0039 μg/mL) than that of fluconazole against Candida albicans and also showed higher activity than that of the other pos. controls. Computational docking experiments indicated that the inhibition of CYP51 involves a coordination bond with iron of the heme group, the hydrophilic H-bonding region, the hydrophobic region, and the narrow hydrophobic cleft. In addition, the activity of the compounds would be enhanced when the side chains were shorter.

Reference of 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.

The present work investigates the effect of complexation with hydroxypropyl-beta-cyclodextrin (HPBCD) and 2-O-methyl-beta-cyclodextrin (2-O-MBCD), on voriconazole solubility, dissolution rate and chem. stability. Drug-cyclodextrin complexes were prepared as aqueous solutions, which were spray-dried, and their properties were compared to wet ground samples and phys. mixtures DSC anal. revealed absence of crystalline voriconazole from spray-dried complexes. FTIR spectroscopy indicated changes in the H-bonding network of the hydroxyl groups of cyclodextrin following drug inclusion. Dissolution rate of voriconazole was significantly higher from spray-dried complexes with either cyclodextrin in comparison with free drug, phys. mixtures, or wet ground mixtures However, two degradation impurities were found in aged samples, with slightly higher impurity level with HPBCD. Performed solubility studies suggested that 2-O-MBCD is more efficient solubilizer. Mol. docking simulations showed a difference in the 1:1 binding affinities and sites, with HPBCD surprisingly forming complexes of much lower energy, thus suggesting a multiple rather than a 1:1 complexation.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 86404-63-9, is researched, Molecular C10H7F2N3O, about Preparation and adsorption properties of Ni(II) ion-imprinted polymers based on synthesized novel functional monomer, the main research direction is nickel imprinted polymer preparation adsorption property.Recommanded Product: 86404-63-9.

In this study, a novel functional monomer N-(1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethyl)acrylamide (NDTEA) was designed and synthesized, and was used to prepare Ni(II) ion-imprinted polymers (Ni(II)-IIPs). Sixteen kinds of Ni(II)-IIP (Ni(II)-IIP1 – 16) and corresponding non-imprinted polymers (NIP1 – 16) were prepared by precipitation polymerization method. After optimized condition experiment, Ni(II)-IIP5 possessed maximum adsorption capacity and better imprinting factor under optimal exptl. conditions which indicated by equilibrium adsorption experiments The morphol. and structural characteristics of Ni(II)-IIP5 were characterized by SEM and Brunauer-Emmett-Teller (BET). The adsorption selectivity of Ni(II)-IIP5 was analyzed by ICP-OES, and the results showed that Ni(II)-IIP5 had favorable selectivity recognition ability for Ni(II) when Cu(II), Co(II), and Cd(II) are used as competitive ions. The kinetic experiment indicated that the performance of Ni(II) adsorption on the surface of Ni(II)-IIP5 obeyed the pseudo-first-order model, and adsorption equilibrium was attained after 15 min. Isothermal adsorption process fitted to Langmuir and Freundlich isothermal adsorption models, simultaneously. The results showed that Ni(II)-IIP5 prepared by using a new functional monomer had better permeation selectivity and higher affinity for Ni(II), which also verified the rationality of the functional monomer design. At the same time, it also provided a broad application prospect for removal of Ni(II) in complex samples.
