Check Digit Verification of cas no

The CAS Registry Mumber 122394-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,3,9 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122394-38:
(8*1)+(7*2)+(6*2)+(5*3)+(4*9)+(3*4)+(2*3)+(1*8)=111
111 % 10 = 1
So 122394-38-1 is a valid CAS Registry Number.

An efficient synthesis of aryl α-keto esters

Ma, Ming,Li, Changkun,Peng, Lingling,Xie, Fang,Zhang, Xiu,Wang, Jianbo

, p. 3927 - 3929 (2005)

A new one-pot approach for the synthesis of aryl α-keto ester based on the diazo transfer and oxidation of diazo group is developed.

Photoinduced Diverse Reactivity of Diazo Compounds with Nitrosoarenes

Roy, Sourav,Kumar, Gourav,Chatterjee, Indranil

supporting information, p. 6709 - 6713 (2021/09/08)

A diverse reactivity of diazo compounds with nitrosoarene in an oxygen-transfer process and a formal [2 + 2] cycloaddition is reported. Nitosoarene has been exploited as a mild oxygen source to oxidize an in situ generated carbene intermediate under visible-light irradiation. UV-light-mediated in situ generated ketenes react with nitosoarenes to deliver oxazetidine derivatives. These operationally simple processes exemplify a transition-metal-free and catalyst-free protocol to give structurally diverse α-ketoesters or oxazetidines.

Carbene-Catalyzed Enantioselective Aromatic N-Nucleophilic Addition of Heteroarenes to Ketones

Liu, Yonggui,Luo, Guoyong,Yang, Xing,Jiang, Shichun,Xue, Wei,Chi, Yonggui Robin,Jin, Zhichao

supporting information, p. 442 - 448 (2019/11/25)

The aromatic nitrogen atoms of heteroarylaldehydes are activated by carbene catalysts to react with ketone electrophiles. Multi-functionalized cyclic N,O-acetal products are afforded in good to excellent yields and optical purities. Our reaction involves the formation of an unprecedented aza-fulvene-type acylazolium intermediate. A broad range of N-heteroaromatic aldehydes and electron-deficient ketone substrates works effectively in this transformation. Several of the chiral N,O-acetal products afforded through this protocol exhibit excellent antibacterial activities against Ralstonia solanacearum (Rs) and are valuable in the development of novel agrichemicals for plant protection.

Displacement of Dinitrogen by Oxygen: A Methodology for the Catalytic Conversion of Diazocarbonyl Compounds to Ketocarbonyl Compounds by 2,6-Dichloropyridine-N-oxide

Yu, Yang,Sha, Qiang,Cui, Hui,Chandler, Kory S.,Doyle, Michael P.

supporting information, p. 776 - 779 (2018/02/09)

Dirhodium(II) catalyzed dinitrogen extrusion from diazocarbonyl compounds by 2,6-dichloropyridine-N-oxide forms ketocarbonyl compounds in near-quantitative yields. Reactions occur at room temperature, and the pyridine product does not coordinate with dirhodium(II) to inhibit catalysis. Anhydrous tricarbonyl compounds, as well as dicarbonyl compounds, are conveniently prepared by this methodology, and they have been used in situ for catalytic ene and aldol transformations.

Enantioselective Iridium-Catalyzed Hydrogenation of α-Keto Amides to α-Hydroxy Amides

Gu, Guoxian,Yang, Tilong,Yu, Ouran,Qian, Hua,Wang, Jiang,Wen, Jialin,Dang, Li,Zhang, Xumu

supporting information, p. 5920 - 5923 (2017/11/10)

A highly enantioselective iridium-catalyzed hydrogenation of α-keto amides to form α-hydroxy amides has been achieved with excellent results (up to >99% conversion and up to >99% ee, TON up to 100?000). As an example, this protocol was applied to the synthesis of (S)-4-(2-amino-1-hydroxyethyl)benzene-1,2-diol, the enantiomer of norepinephrine, which is widely used as an injectable drug for the treatment of critically low blood pressure. Density functional theory (DFT) calculations were also carried out to reveal the reaction mechanism.

P(NMe2)3-Mediated Umpolung Alkylation and Nonylidic Olefination of α-Keto Esters

Wang, Sunewang Rixin,Radosevich, Alexander T.

, p. 3810 - 3813 (2015/08/18)

A commercial phosphorus-based reagent (P(NMe2)3) mediates umpolung alkylation of methyl aroylformates with benzylic and allylic bromides, leading to either Barbier-type addition or ylide-free olefination products upon workup. The reaction sequence is initiated by a two-electron redox addition of the tricoordinate phosphorus reagent with an α-keto ester compound (Kukhtin-Ramirez addition). A mechanistic rationale is offered for the chemoselectivity upon which the success of this nonmetal mediated C-C bond forming strategy is based.

Electrochemical synthesis of the aryl α-ketoesters from acetophenones mediated by Ki

Zhang, Zhenlei,Su, Jihu,Zha, Zhenggen,Wang, Zhiyong

supporting information, p. 17711 - 17714 (2014/01/17)

Two C-O bonds formed in one step: The oxidative coupling reaction of acetophenones with alcohol was developed by a dioxygen activation to afford α-ketoesters under electrochemical conditions. This novel transformation not only provides a simple and efficient approach to synthetize α-ketoester derivatives, but also invents a new strategy to construct a C-O bond by virtue of an anode oxidation (see scheme).

A practical and efficient synthesis of various 1,2,5-tricarbonyl compounds is described. The synthesis has been carried out by a conjugate addition of methyl cyanoacetate to the β-position of α,β-unsaturated carbonyl compounds and a subsequent copper(I) iodide-catalyzed aerobic oxidation. In addition, various α-aryl- and α-alkyl-α-keto esters have been synthesized using a similar approach. Copyright
