Check Digit Verification of cas no

The CAS Registry Mumber 15186-48-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,8 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15186-48:
(7*1)+(6*5)+(5*1)+(4*8)+(3*6)+(2*4)+(1*8)=108
108 % 10 = 8
So 15186-48-8 is a valid CAS Registry Number.

An Esterase-like Lyase Catalyzes Acetate Elimination in Spirotetronate/Spirotetramate Biosynthesis

Lees, Nicholas R.,Han, Li-Chen,Byrne, Matthew J.,Davies, Jonathan A.,Parnell, Alice E.,Moreland, Pollyanna E. J.,Stach, James E. M.,van der Kamp, Marc W.,Willis, Christine L.,Race, Paul R.

, p. 2305 - 2309 (2019)

Spirotetronate and spirotetramate natural products include a multitude of compounds with potent antimicrobial and antitumor activities. Their biosynthesis incorporates many unusual biocatalytic steps, including regio- and stereo-specific modifications, cyclizations promoted by Diels–Alderases, and acetylation-elimination reactions. Here we focus on the acetate elimination catalyzed by AbyA5, implicated in the formation of the key Diels–Alder substrate to give the spirocyclic system of the antibiotic abyssomicin C. Using synthetic substrate analogues, it is shown that AbyA5 catalyzes stereospecific acetate elimination, establishing the (R)-tetronate acetate as a biosynthetic intermediate. The X-ray crystal structure of AbyA5, the first of an acetate-eliminating enzyme, reveals a deviant acetyl esterase fold. Molecular dynamics simulations and enzyme assays show the use of a His-Ser dyad to catalyze either elimination or hydrolysis, via disparate mechanisms, under substrate control.

Synthesis of (-)-tetrodotoxin: Preparation of an advanced cyclohexenone intermediate

Taber, Douglass F.,Storck, Pierre H.

, p. 7768 - 7771 (2003)

The preparation of an advanced intermediate toward the enantioselective synthesis of tetrodotoxin is outlined. The enantiomerically pure cyclopentene 15 was generated from ketone 14 by alkylidene carbene insertion with retention of absolute configuration. An ozonolysis/aldol sequence first produced the trans cyclohexenone, which upon epimerization gave the more stable cis enone 18.

Synthesis, spectroscopic characterization and biological properties of new natural aldehydes thiosemicarbazones

Tarasconi, Pieralberto,Capacchi, Silvia,Pelosi, Giorgio,Cornia, Mara,Albertini, Roberto,Bonati, Antonio,Dall'Aglio, Pier Paolo,Lunghi, Paolo,Pinelli, Silvana

, p. 157 - 162 (2000)

As part of a research programme aimed at the synthesis of compounds with antiviral, antibacterial and antitumor properties and their spectroscopic characterization, new thiosemicarbazones deriving from natural aldehydes have been investigated. These substances contain in the same molecule both a chain with nucleophilic centres N, S with tubercolostatic activity, and a glycosidic or alkyl moiety (modified glycosides and nucleosides have recently received a great deal of attention in the fields of neoplastic diseases and viral infections). In this paper the synthesis and the characterization of these compounds by means of 1H NMR, IR, and MS techniques is reported. Biological studies have involved both inhibition of cell proliferation and apoptosis tests on human leukemia cell line U937. (C) 2000 Elsevier Science Ltd.

A nitrilase-mediated entry to 4-carboxymethyl-β-lactams from chemically prepared 4-(cyanomethyl)azetidin-2-ones

Decuyper, Lena,Piens, Nicola,Mincke, Jens,Bomon, Jeroen,De Schrijver, Bert,Mollet, Karen,De Winter, Karel,Desmet, Tom,D'Hooghe, Matthias

, p. 54573 - 54579 (2016)

(3R,4S)-3-Alkoxy/aryloxy-4-(cyanomethyl)azetidin-2-ones were efficiently prepared from readily available 1,2:5,6-di-O-isopropylidene-d-mannitol by means of a classical organic synthesis approach via 4-hydroxymethyl-β-lactams as key intermediates. The corresponding 4-carboxymethyl-β-lactams were subsequently obtained after selective hydrolysis of the nitrile functionality by means of a nitrilase enzyme without affecting the sensitive four-membered ring system, hence overcoming the difficulties associated with the chemical hydrolysis approach. Thus, the implementation of a biocatalytic step allows a convenient synthetic route to new 4-carboxymethyl-β-lactams as versatile building blocks for further elaboration.

SYNTHESIS OF A NOVEL PROSTAGLANDIN H2 (PGH2) ANALOGUE

Elder, John S.,Mann, John,Walsh, E. Brian

Synthesis of the AB ring system of clifednamide utilizing Claisen rearrangement and Diels-Alder reaction as key steps

Loke, Inga,Bentzinger, Guillaume,Holz, Julia,Raja, Aruna,Bhasin, Aman,Sasse, Florenz,K?hn, Andreas,Schobert, Rainer,Laschat, Sabine

, p. 884 - 894 (2016)

In order to construct the functionalized AB ring system of clifednamide, member of the class of macrocyclic tetramic acid lactams, a synthesis was developed which utilized an Ireland-Claisen rearrangement and an intramolecular Diels-Alder reaction. Starting from di-O-isopropylidene-d-mannitol the allyl carboxylate precursor for the sigmatropic rearrangement was prepared. This rearrangement proceeded diastereoselectively only in the presence of an allyl silyl ether instead of the parent enone in the side chain, as suggested by deuteration experiments. A subsequent Diels-Alder reaction yielded the target ethyl hexahydro-1H-indene-carboxylate with high diastereoselectivity. Quantum-chemical investigations of this intramolecular Diels-Alder reaction support the proposed configuration of the final product.

Diastereomeric enols and enol derivatives of 8-fluoro-5,11-dihydro-10H- dibenzo[a,d]cyclohepten-10-one with a chiral 11-substituent

Compernolle, Frans,Toppet, Suzanne,Brossette, Thierry,Mao, Hua,Koukni, Mohamed,Kozlecki, Tomasz,Medaer, Bart,Guillaume, Michel,Lang, Yolande,Leurs, Stef,Hoornaert, Georges J.

, p. 1586 - 1592 (2006)

Aldol condensation of 8-fluoro-5,11-dihydro-10H-dibenzo[a,d]cyclohepten-10- one and (4S)-2,2-dimethyl-1,3-dioxolane-4-carbaldehyde provides access to the corresponding (E,Z)-α,β-unsaturated ketones with a (4R)-chiral 11-substituent. Subsequent hydrogenation affords a mixture of (11R)/ (11S)-epimeric ketones, which undergoes base-catalysed equilibration resulting in selective crystallisation of the (11R) epimer. The enol intermediate and acyclic enol derivatives are shown to exist as two slowly interconverting conformers with a high inversion barrier of the 10,11-disubstituted ring.

Nitrosocarbonyl Carbohydrate Derivatives: Hetero Diels-Alder and Ene Reaction Products for Useful Organic Synthesis

Corti, Marco,Leusciatti, Marco,Moiola, Mattia,Mella, Mariella,Quadrelli, Paolo

, p. 574 - 586 (2020/10/06)

The generation and trapping of two new nitrosocarbonyl intermediates bearing carbohydrate-based chiral substituents is achieved by the mild oxidation of the corresponding nitrile oxides with tertiary amine N -oxides. Their capture with suitable dienes and alkenes afforded the corresponding hetero Diels-Alder cycloadducts and ene adducts from fair to excellent yields. The entire methodology looks highly promising by the easy conversion of aldoximes into hydroxymoyl halides, widening the access to nitrosocarbonyls, versatile tools in organic synthesis.

Total Synthesis of the Putative Structure of Asperipin-2a and Stereochemical Reassignment

Hutton, Craig A.,Shabani, Sadegh,White, Jonathan M.

supporting information, p. 7730 - 7734 (2020/10/09)

The total synthesis of the putative structure of asperipin-2a is described. The synthesis features ether cross-links between the phenolic oxygen of Tyr6 and the β position of Tyr3 and the phenolic oxygen of Tyr3 and the β position of Hpp1 in the unique 17- and 14-membered bicyclic structure of asperipin-2a, respectively. The synthesized putative structure does not match the natural product, and a stereochemical reassignment is postulated.
