81447-37-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81447-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,4 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81447-37:
(7*8)+(6*1)+(5*4)+(4*4)+(3*7)+(2*3)+(1*7)=132
132 % 10 = 2
So 81447-37-2 is a valid CAS Registry Number.

Spiro cyclohexadienones from the reaction of phenolic enaminone derivatives with hypervalent iodine reagents

Asmanidou, Anna,Papoutsis, Ioannis,Spyroudis, Spyros,Varvoglis, Anastasios

, p. 874 - 879 (2000)

Phenolic enamino compounds, prepared from 2-(4-hydroxyphenyl)-ethylamine and the corresponding β-keto carbonyl compounds, afford spiro cyclohexadienone derivatives on reaction with hypervalent iodine reagents.

Oxidative umpolung ?±-alkylation of ketones

Shneider, O. Svetlana,Pisarevsky, Evgeni,Fristrup, Peter,Szpilman, Alex M.

supporting information, p. 282 - 285 (2015/03/05)

We disclose a hypervalent iodine mediated ?±-alkylative umpolung reaction of carbonyl compounds with dialkylzinc as the alkyl source. The reaction is applicable to all common classes of ketones including 1,3-dicarbonyl compounds and regular ketones via their lithium enolates. The ?±-alkylated carbonyl products are formed in up to 93% yield. An ionic mechanism is inferred based on meticulous analysis, NMR studies, trapping and crossover experiments, and computational studies.

Design, synthesis and RON receptor tyrosine kinase inhibitory activity of new head groups analogs of LCRF-0004

Raeppel, Franck,Raeppel, Stéphane L.,Therrien, Eric

, p. 3810 - 3815 (2015/08/24)

New heteroarylcarboxamide head groups substituted with two aromatic rings analogs of thieno[3,2-b]pyridine-based kinase inhibitor LCRF-0004 were designed and synthesized. Potent inhibitors of RON tyrosine kinase with various level of selectivity for c-Met RTK were obtained.

Preparation of iodonium ylides: Probing the fluorination of 1,3-dicarbonyl compounds with a fluoroiodane

Geary, Gemma C.,Hope, Eric G.,Singh, Kuldip,Stuart, Alison M.

, p. 16501 - 16506 (2015/03/04)

The isolation of iodonium ylide 8, from the reaction of fluoroiodane 1 with ethyl 3-oxo-3-phenylpropanoate 5 in the presence of potassium fluoride, provides strong evidence that 1,3-dicarbonyl compounds undergo an addition reaction with fluoroiodane 1 to form an iodonium intermediate which can be deprotonated to generate an iodonium ylide. In the presence of TREAT-HF, however, the iodonium intermediate reacts to form the 2-fluoro-1,3-dicarbonyl product and we propose that fluoroiodane 1 simulates electrophilic fluorination via an addition/substitution mechanism. Further evidence to support this mechanism was obtained by successfully reacting the isolated iodonium ylide 8 with TREAT-HF, hydrochloric acid, acetic acid and p-toluenesulfonic acid to form the 2-fluoro-, 2-chloro-, 2-acetyl- and 2-tosyl-1,3-ketoesters respectively.

An iodobenzene-catalysed domino route toward quinoxaline derivatives from simple ketones and o-phenylenediamines in one pot

Li, Xiaoqing,Zhou, Can,Hu, Zhiyan,Xu, Xiangsheng

, p. 579 - 581 (2013/10/22)

An iodobenzene-catalysed domino route to quinoxalines from ketones and o-phenylenediamines in one pot has been developed. This transformation consisted of the generation of Koser's generation, α-tosyloxylation of ketones, nucleophilic substitution and intramolecular dehydration with o-phenylenediamines, and dehydrogenation.

Synthesis of imidazo[1,2-a]pyridines by the bis(acetyloxy)(phenyl)- λ3-iodane-Mediated oxidative coupling of 2-aminopyridines with β-keto esters and 1,3-diones

Wang, Xianpei,Ma, Lijuan,Yu, Wei

scheme or table, p. 2445 - 2453 (2011/09/15)

Imidazo[1,2-a]pyridine-3-carboxylates can be prepared directly from 2-aminopyridines and β-keto esters by using bis(acetyloxy)(phenyl)- λ3-iodane as an oxidant and boron trifluoride etherate as a catalyst. The amount of catalyst plays a key rol

Iodoarene-mediated α-tosyloxylation of ketones with MCPBA and p-toluenesulfonic acid

Tanaka, Ayumi,Moriyama, Katsuhiko,Togo, Hideo

experimental part, p. 1853 - 1858 (2011/09/16)

Alkyl aryl ketones and dialkyl ketones could be converted into the corresponding α-tosyloxy ketones by the reaction with MCPBA and p-toluenesulfonic acid monohydrate (PTSA ? H2O) in the presence of a catalytic amount of molecular iodine (I

Various α-oxygen functionalizations of β-dicarbonyl compounds mediated by the hypervalent iodine(III) reagent p-iodotoluene difluoride with different oxygen-containing nucleophiles

Jun, Yu,Jun, Tian,Chi, Zhang

experimental part, p. 531 - 546 (2010/06/13)

p-Iodotoluene difluoride (p-Tol-IF2) has been found to be a general reagent for the effective introduction of various oxygen-containing functionalities including tosyloxy, mesyloxy, acetoxy, phosphoryloxy, methoxy, ethoxy and isopropoxy at the α-position of β-dicarbonyl compounds. These transformations can be readily realized by the use of the combined reagent of p-iodotoluene difluoride and various oxygen-containing nucleophilic compounds such as p-toluenesulfonic acid, methanesulfonic acid, acetic acid, diphenyl phosphate, methanol, ethanol and propan-2-ol under mild conditions, respectively. And, the in situ generated hypervalent iodine(III) species via ligand exchange between p-iodotoluene difluoride and the respective oxygen-containing nucleophiles are believed to be the real oxidizing agents in such transformations.

Novel preparation of polymer-supported iodobenzene and its synthetic utility as a recyclable reagent with m-chloroperbenzoic acid

Suzuki, Yuhsuku,Togo, Hideo

experimental part, p. 2355 - 2360 (2010/09/18)

Three novel polymer-supported iodobenzene compounds A0, A 6, and A10 were prepared from the reaction of commercially available cross-linked poly(p-chloromethyl)styrene with m-iodobenzylalcohol, 6-(m-iodobenzyloxy)-1-hexanol, and 10-(m-iodobenzyloxy)-1-decanol. Their catalytic reactivity and reusability for the oxidative α-tosyloxylation of ketones and the cyclization of N-methoxy-2-arylethanesulfonamides in the presence of m-chloroperbenzoic acid (mCPBA) were confirmed to provide -tosyloxyketones and N-methoxy-3,4-dihydro-2,1-benzothiazine-2,2-dioxides, respectively, in good yields.
