A polystyrene-supported isothiourea catalyst, based on the homogeneous catalyst HyperBTM, has been prepared and used for the acylative kinetic resolution of secondary alcohols. A wide range of alcohols, including benzylic, allylic, and propargylic alcohols, cycloalkanol derivatives, and a 1,2-diol, has been resolved using either propionic or isobutyric anhydride with good to excellent selectivity factors obtained (28 examples, s values up to 600). The catalyst can be recovered and reused by a simple filtration and washing sequence, with no special precautions needed. The recyclability of the catalyst was demonstrated (15 cycles) with no significant loss in either activity or selectivity. The recyclable catalyst was also used for the sequential resolution of 10 different alcohols using different anhydrides with no cross-contamination between cycles. Finally, successful application in a continuous flow process demonstrated the first example of an immobilized Lewis base catalyst used for the kinetic resolution of alcohols in flow.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4175-77-3, Name is 2,4-Dibromothiazole, molecular formula is C3HBr2NS. In a Article£¬once mentioned of 4175-77-3, Formula: C3HBr2NS

Functionalized heterocyclic zinc reagents are easily aminated by an oxidative amination reaction of zinc amidocuprates prepared from various lithium amides. For the oxidation step, PhI(OAc)2 proved to be the best reagent. The required heterocyclic zinc organometallics can be prepared either by direct metalation, by magnesium insertion in the presence of ZnCl 2, or by transmetalation of a suitable magnesium reagent. Furthermore, we report a new ring-closing reaction involving an intramolecular oxidative amination reaction. This reaction allows the preparation of tetracyclic heterocycles containing furan, thiophene, or indole rings. Funktionalisierte heterozyklische Amine koennen durch oxidative Aminierung von Zink-Amidocupraten dargestellt warden, welche durch die Reaktion einer Reihe von Lithiumamiden mit funktionalisierten Zinkreagenzien zugaenglich sind. Dabei hat sich Iodbenzoldiacetat PhI(OAc)2 als optimales Oxidationsmittel herausgestellt. Die notwendigen Organozinkverbindungen koennen durch direkte Metallierung, Magnesiuminsertion in Gegenwart von ZnCl2 oder durch Transmetallierung geeigneter Organomagnesiumreagenzien dargestellt werden. Darueber hinaus berichten wir von einer neuen Ringschlussreaktion mittels intramolekularer oxidativer Aminierung. Diese Reaktion ermoeglicht die Darstellung tetrazyklischer Heterozyklen mit Furan-, Thiophen-, oder Indolgeruesten. Copyright

80945-86-4, Name is 6-Bromo-2-chlorobenzothiazole, molecular formula is C7H3BrClNS, belongs to thiazole compound, is a common compound. In a patnet, once mentioned the new application about 80945-86-4, COA of Formula: C7H3BrClNS

A copper-mediated difluoromethylenation of o-bromophenols with trifluoromethanethiolate is described. This one-pot protocol proceeds through an intermolecular addition of S=CF2 (resulting from the decomposition of trifluoromethanethiolate) to o-bromophenols followed by intramolecular C-S coupling to form 2,2-difluoro-1,3-benzoxathioles. This method is compatible with a broad range of substrates and enables the late-stage difluoromethylenation of several functionally dense druglike o-bromophenols.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 348-40-3, C7H5FN2S. A document type is Article, introducing its new discovery., Application In Synthesis of 6-Fluorobenzo[d]thiazol-2-amine

There is an urgent need for structurally novel anti-norovirus agents. In this study, we describe the synthesis, anti-norovirus activity, and structure-activity relationship (SAR) of a series of heterocyclic carboxamide derivatives. Heterocyclic carboxamide 1 (50% effective concentration (EC50)=37 muM) was identified by our screening campaign using the cytopathic effect reduction assay. Initial SAR studies suggested the importance of halogen substituents on the heterocyclic scaffold and identified 3,5-di-boromo-thiophene derivative 2j (EC50=24 muM) and 4,6-di-fluoro-benzothiazole derivative 3j (EC50=5.6 muM) as more potent inhibitors than 1. Moreover, their hybrid compound, 3,5-di-bromo-thiophen-4,6-di-fluoro-benzothiazole 4b, showed the most potent anti-norovirus activity with a EC50 value of 0.53 muM (70-fold more potent than 1). Further investigation suggested that 4b might inhibit intracellular viral replication or the late stage of viral infection.

The invention provides a method for detection of active form of analytes in a sample and/or for determination of ability of tested substances to bind to the active site of these analytes, comprising the following steps: a) analyte or group of analytes from the sample is immobilized on the surface of a solid carrier either by non-specific non-covalent adsorption or by covalent binding of surface functional groups of the analyte and corresponding functional groups of the solid carrier, or preferably via a binding molecule which is bound to the surface of the solid carrier before immobilization of the analyte or group of analytes and is capable of selectively binding the analyte or group of analytes contained in the sample during incubation of the solid carrier with the sample; b) analyte or group of analytes is incubated with a detection probe which binds selectively to the analyte or group of analytes via a compound for selective binding to the analyte active site; whereas the probe consists of a low molecular compound for selective binding to the analyte active site; an oligonucleotide tag, optionally with a covalently attached fluorophore, biotin or a chemical group, and a chemical linker covalently linking the compound for selective binding to the analyte active site and the oligonucleotide tag; c) then the solid carrier is washed to remove unbound detection probe; and subsequently, the amount of bound detection probe is determined, whereas this amount is directly proportional to the amount of the analyte or group of analytes in the sample. The described method has broad application in medicine. Given the exceptional sensitivity of only a few dozen molecules, it provides the ability to determine the protein markers in blood in a concentration yet undetectable.
