In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Catalytic Enantio- and Diastereoselective Cyclopropanation of 2-Azadienes for the Synthesis of Aminocyclopropanes Bearing Quaternary Carbon Stereogenic Centers, published in 2019-09-20, which mentions a compound: 16004-15-2, mainly applied to enantioselective diastereoselective aminocyclopropane preparation cyclopropanation azadiene diazoester; terminal internal azadiene donor acceptor carbene diazoester cyclopropanation, Category: piperazines.

We report the catalytic enantio- and diastereoselective preparation of aminocyclopropanes by the cyclopropanation of terminal and (Z)-internal 2-azadienes with donor/acceptor carbenes derived from α-diazoesters. The resulting cyclopropanes bear quaternary carbon stereogenic centers vicinal to the amino-substituted carbon and are formed as a single diastereomer in up to 99:1 er and 97% yield with 0.5 mol % of Rh2(DOSP)4 and only 1.5 equiv of the diazo reagent. Transformations with internal azadienes afford cyclopropanes with three contiguous stereogenic centers.

Metalation of hypercloso-dodecaborane-appended aryl iodide B12(OCH2C6H4I)12 with Au(I) Me-DalPhos (L) complex LAuCl gives rise to Au(III)-functionalized cage [B12[OCH2C6H4Au(Cl)(Me-DalPhos)]12][SbF6]11 (1), which was converted into thioethers [B12[OCH2C6H4SR]12]2- (2-20) by reaction with thiols RSH and used for further layer-by-layer nanocluster growth. For decades, chemists have striven to mimic the intricate design and diverse functions of naturally occurring systems through the bioinspired synthesis of programmable inorganic nanomaterials. The development of thiol-capped gold nanoparticles (AuNPs) has driven advancement in this area; however, although versatile and readily accessible, hybrid AuNPs are rarely atomically precise, which limits control over their surface topol. and therefore the study of complex structure-function relationships. Here, we present a bottom-up approach to the systematic assembly of atomically precise hybrid nanoclusters employing a strategy that mimics the synthetic ease with which thiol-capped AuNPs are normally constructed, while producing well-defined covalent nanoscale assemblies with diverse surface topologies. For the first time, using a structurally characterized cluster-based organometallic building block, we demonstrate the systematic synthesis of nanoclusters with multivalent binding capabilities to complex protein targets.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions.

Keywords: keto esters chemoselective regioselective enantioselective preparation; alkyl diazoester ketone scandium catalyst homologation chemoselective regioselective enantioselective. Let’s learn more about this compound (cas:16004-15-2).

The homologation of ketones with diazo compounds was a useful strategy to synthesize one-carbon chain-extended acyclic such as PhC(O)CMeCO2MeR [R = allyl, Bn, CH2(2-naphthyl), etc.] or ring-expanded cyclic ketones e.g., I. However, the asym. homologation of acyclic ketones with α-diazo esters remains a challenge due to the lower reactivity and complicated selectivity. Herein, the enantioselective catalytic homologation of acetophenone and related derivatives with α-alkyl α-diazo esters was reported utilizing a chiral scandium(III) N,N’-dioxide as the Lewis acid catalyst. This reaction supplies a highly chemo-, regio-, and enantioselective pathway for the synthesis of optically active β-keto esters with an all-carbon quaternary center through highly selective alkyl-group migration of the ketones. Moreover, the ring expansion of cyclic ketones was accomplished under slightly modified conditions, affording a series of enantioenriched cyclic β-keto esters. D. functional theory calculations was carried out to elucidate the reaction pathway and possible working models that could explain the observed regio- and enantioselectivity.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-(Bromomethyl)-4-iodobenzene, is researched, Molecular C7H6BrI, CAS is 16004-15-2, about Structural modification on rupestonic acid leads to highly potent inhibitors against influenza virus.Product Details of 16004-15-2.

Influenza viruses are responsible for seasonal epidemics and occasional pandemics, which cause significant morbidity and mortality. Although several drugs (adamantanes and neuraminidase inhibitors) are available in the market, the worldwide spread of drug-resistant influenza strains poses an urgent need for novel antiviral drugs. Artemisia rupestris L. is a folk medicine used to treat cold. In this paper, we structurally modified rupestonic acid, a bioactive component of A. rupestris, to synthesize a series of 2-substituted rupestonic acid Me esters (3a-3o). Their structures were fully characterized by 1H NMR, 13C NMR, HRMS spectra. Among them, compounds 3b and 3c exhibited potent activities against influenza H1N1 with micromolar IC50 values and might serve as new lead compounds for the treatment of influenza.

Let’s take a look at the latest research on this compound (cas:16004-15-2).

A new Ph (3-phenylpyrrolidin-3-yl)sulfone series of RORγt inverse agonists was discovered utilizing the binding conformation of previously reported bicyclic sulfonamide 1. Through a combination of structure-based design and structure-activity relationship studies, a polar set of amides at N1-position of the pyrrolidine ring and perfluoroisopropyl group at para-position of the 3-Ph group were identified as critical structural elements to achieve high selectivity against PXR, LXRα, and LXRβ. Further optimization led to the discovery of (1R,4r)-4-((R)-3-((4-fluorophenyl)sulfonyl)-3-(4-(perfluoropropan-2-yl)phenyl)pyrrolidine-1-carbonyl)cyclohexane-1-carboxylic acid (26), which displayed excellent selectivity, desirable liability and pharmacokinetic properties in vitro, and a good pharmacokinetic profile in mouse. Oral administration of 26 demonstrated dose-dependent inhibition of IL-17 production in a mouse IL-2/IL-23-induced pharmacodynamic model and biol.-like efficacy in an IL-23-induced mouse acanthosis model.
