It was found that the reaction of 5-arylfurfurilamines with maleic anhydride leads to the formation of 6-aryl-3a,6-epoxyisoindole-7-carboxylic acids (the cyclic form), which in solution are in dynamic equilibrium with N-furfurylmaleinamides (the open form). During the esterification of these tautomeric mixtures with methanol in the presence of a catalytic amount of sulfuric acid, methyl esters of 5-aryl-7a-hydroxy-7-methoxy-3-oxo-2,3,3a,4,7,7a-hexahydro-1H-isoindole-4-carboxylic acids, unexpected cleavage products of the 3a,6-oxo bridge of the cyclic form, are formed diastereospecifically. The structure of the obtained products was confirmed by X-ray structural analysis.

A series of isothiazole dioxides was synthesized and evaluated as inhibitors of protein farnesyltransferase from the parasite that causes African sleeping sickness (Trypanosoma brucei). The most potent compound in the series inhibited the parasite enzyme with an IC50 of 2 muM and blocked the growth of the bloodstream parasite in vitro with an ED50 of 10 muM. The same compound inhibited rat protein farnesyltransferase and protein geranylgeranyltransferase type I only at much higher concentration. (C) 2002 Elsevier Science Ltd. All rights reserved.

Application In Synthesis of Bis(2-ethylhexyl) 3,4,5,6-tetrabromophthalate, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. 26040-51-7, Name is Bis(2-ethylhexyl) 3,4,5,6-tetrabromophthalate, SMILES is O=C(OCC(CC)CCCC)C1=C(Br)C(Br)=C(Br)C(Br)=C1C(OCC(CC)CCCC)=O, belongs to isothiazole compound. In a article, author is Cutri, CCC, introduce new discover of the category.

The isothiazole derivative 3-methylthio-5-(4-OBn-phenyl)-4-isothiazolecarbonitrile, coded IS-50, which in previous studies had exhibited a broad antipicornavirus spectrum of action, was selected as the model for the synthesis of a new series of 3-methylthio-5-aryl-4-isothiazolecarbonitriles. These compounds were prepared in good yield (from 66 to 82%) by alkylation of 3-methylthio-5-(4-hydroxyphenyl)-4-isothiazolecarbonitrile with suitable bromides in the presence of acetone; only the 4-cyanophenoxy derivatives were obtained in a yield of less than 30%. All the compounds were screened against a panel of 17 representative human rhinovirus (HRV) serotypes belonging to both A and B groups, enteroviruses polio 1, ECHO 9 and Coxsackie B1, cardiovirus EMC, measles virus, and herpes simplex virus type I (HSV-1). Our results demonstrate that HRV 86 (group A) and HRVs 39 and 89 (group B) are the rhinovirus serotypes more susceptible to the action of these compounds. Isothiazole derivatives with a longer intermediate alkyl chain exhibited good activity against polio 1 and ECHO 9. The compound bearing a butyl group between the two phenoxy rings showed the lowest IC50 against Coxsackie B1 and measles viruses. No activity against HSV-1 was detected with any of the compounds screened. (C) 2002 Published by Elsevier Science B.V.

In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. 26040-51-7, Name is Bis(2-ethylhexyl) 3,4,5,6-tetrabromophthalate, SMILES is O=C(OCC(CC)CCCC)C1=C(Br)C(Br)=C(Br)C(Br)=C1C(OCC(CC)CCCC)=O, in an article , author is Zapol’skii, Viktor A., once mentioned of 26040-51-7, HPLC of Formula: https://www.ambeed.com/products/26040-51-7.html.

The nitropolychlorobutadienes 3, 4 are valuable building blocks for various amination and successive heterocyclization products. Nucleophilic substitution reactions of the partially protected, bioactive amines 1, 2 with either vinyl, imidoyl or carbonyl chlorides result in the formation of the enamines 11, 12, 13, 16, 25, the amidine 6, and the amides 20, 21, respectively. In the following, cyclization to the highly functionalized pyrazoles 27, 28, pyrimidine 26 and pyridopyrimidine 24 succeeded. Deprotection of 21, 12 and 28 proved to be only partially feasible.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield.
