NEW PHOSPHORYLATING AGENTS FOR GENERAL SYNTHESIS OF MIXED PHOSPHATE ESTERS

An effective procedure has been developed for the general synthesis of mixed alkyl or aryl phosphate esters by metal-catalyzed phosphorylation of alcohols with aryl bis(2-oxo-3-oxazolinyl)phosphinate.Among metallic acetylacetonates examined as catalysts, the zirconium complex was the most effective as in activity order of Zr(IV)> Ce(III)> Zn(II)> Mn(III)> Mn(II)-complexes.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 497-25-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 497-25-6, in my other articles.

Synthetic study of diversifolin: The construction of 11-oxabicyclo[6.2.1] undec-3-ene core using ring-closing metathesis

Stereoselective synthesis of a potential intermediate bearing 11-oxabicyclo[6.2.1]undec-3-ene core, a common scaffold of biologically active germacrane-type sesquiterpenes, has been achieved. Synthetic features involve formal 1,3-asymmetric induction, unusual ring-closing metathesis constructing a 10-membered carbocycle system, and unique lactone transposition.

Cobalt-catalyzed intermolecular C(sp2)-O cross-coupling

Cobalt(II)-catalyzed C(sp2)-O cross-coupling between aryl/heteroaryl alcohols and vinyl/aryl halides in the presence of CuI has been achieved under ligand-free conditions. In this reaction, copper plays a significant role in transmetalation rather than being directly involved in the C-O coupling. This unique Co/Cu-dual catalyst system provides an easy access to a library of aryl-vinyl, heteroaryl-styryl, aryl-aryl, and heteroaryl-heteroaryl ethers in the absence of any ligand or additive.

Revitalizing the drug pipeline: AntibioticDB, an open access database to aid antibacterial research and development

The current state of antibiotic discovery, research and development is insufficient to respond to the need for new treatments for drug-resistant bacterial infections. The process has changed over the last decade, with most new agents that are in Phases 1-3, or recently approved, having been discovered in small- and medium-sized enterprises or academia. These agents have then been licensed or sold to large companies for further development with the goal of taking them to market. However, early drug discovery and development, including the possibility of developing previously discontinued agents, would benefit from a database of antibacterial compounds for scrutiny by the developers. This article describes the first free, open-access searchable database of antibacterial compounds, including discontinued agents, drugs under pre-clinical development and those in clinical trials: AntibioticDB (AntibioticDB.com). Data were obtained from publicly available sources. This article summarizes the compounds and drugs in AntibioticDB, including their drug class, mode of action, development status and propensity to select drug-resistant bacteria. AntibioticDB includes compounds currently in pre-clinical development and 834 that have been discontinued and that reached varying stages of development. These may serve as starting points for future research and development.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 39093-93-1!, 497-25-6

Regioselective 4-amino-de-chlorination of trichloro- and dichloro-pyrimidines with N-sodium carbamates

4-N-Alkoxycarbonylamino-2,6-dichloro- and -2-chloro-pyrimidines have been synthesized in good to excellent regioselectivity and yields from N-sodium carbamates and, respectively, 2,4,6-trichloropyrimidine and 2,4-dichloropyrimidine, in DMF, rt, 15-30 min. The reaction is effective also with 4,6-dichloropyrimidine, producing 4-N-alkoxycarbonylamino-6-chloropyrimidines in good yields. Some conformational features of 4-N-alkoxycarbonylamino-2,6-dichloro-pyrimidines have been investigated by X-ray diffraction and 1H NMR spectroscopy.

Copper-catalyzed amination of aryl and alkenyl electrophiles

The copper-catalyzed arylation and vinylation of nitrogen nucleophiles is a highly versatile method for the construction of sp2C?N bonds. Copper-catalyzed C?N bond formation has an extensive history and the field has been reinvigorated with the development of ligand-promoted catalyst systems that provide general and effective reactions under relatively mild conditions. Copper promotes arylation and vinylation of a wide range of nitrogen nucleophiles, including amines, nitrogen heterocycles, and amide derivatives. The reactivity profile is complementary to that of palladium and often offers orthogonal chemoselectivity. This chapter presents a thorough overview of the copper-catalyzed coupling of aryl and vinyl halides with nitrogen nucleophiles. Current understanding of the mechanism of this process is presented along with a detailed overview of the scope and limitations of this reaction along with optimal reaction conditions for the coupling of various nitrogen nucleophile classes.

Thermal Degradation Pathways of Aqueous Diamine CO2 Capture Solvents

Diamines have shown promise as CO2 capture solvents, yet very little is known about their pathway for thermal degradation. In this study, diamine thermal degradation was quantitatively monitored in lab-scale experiments on four aqueous diamine solvents; ethylenediamine (EDA) 1,2-propanediamine (1,2-DAP), 1,3-diaminopropane (1,3-DAP) and N-methyl-1,2-ethanediamine (N-MEDA), to gain a more comprehensive understanding of their degradation pathway(s). The major degradation products were identified by high resolution time-of-flight mass spectrometry (TOF-MS). Degradation pathways were proposed showing that the primary thermal degradation route for this class of amine are through carbamate formation followed by intermolecular cyclization to form an imidazolidinone or nucleophilic attack by a free amine to form a diamine urea.

Synthesis of stable derivatives of cycloprop-2-ene carboxylic acid

(Chemical Equation Presented) Large-scale syntheses of 3-(cycloprop-2-en-1- oyl)oxazolidinones from acetylene and ethyl diazoacetate are described. Unlike other cyclopropenes that bear a single substitutent at C-3, these compounds are stable to long-term storage. Although the cyclopropene derivatives are unusually stable, they are reactive toward cyclic and acyclic dienes in stereoselective Diels-Alder reactions.

Synthesis and quantitative structure-activity relationship of fatty acid amide hydrolase inhibitors: Modulation at the N-portion of biphenyl-3-yl alkylcarbamates

Alkylcarbamic acid biphenyl-3-yl esters are a class of fatty acid amide hydrolase (FAAH) inhibitors that comprises cyclohexylcarbamic acid 3?-carbamoylbiphenyl-3-yl ester (URB597), a compound with analgesic, anxiolytic-like and antidepressant-like properties in rat and mouse models. Here, we extended the structure-activity relationships (SARs) for this class of compounds by replacing the cyclohexyl ring of the parent compound cyclohexylcarbamic acid biphenyl-3-yl ester (URB524) (FAAH IC50 = 63 nM) with a selected set of substituents of different size, shape, flexibility, and lipophilicity. Docking experiments and linear interaction energy (LIE) calculations indicated that the N-terminal group of O-arylcarbamates fits within the lipophilic region of the substrate-binding site, mimicking the arachidonoyl chain of anandamide. Significant potency improvements were observed for the beta-naphthylmethyl derivative 4q (IC50 = 5.3 nM) and its 3?-carbamoylbiphenyl-3-yl ester 4z (URB880, IC50 = 0.63 nM), indicating that shape complementarity and hydrogen bonds are crucial to obtain highly potent inhibitors.
