Check Digit Verification of cas no

The CAS Registry Mumber 1196-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1196-38:
(6*1)+(5*1)+(4*9)+(3*6)+(2*3)+(1*8)=79
79 % 10 = 9
So 1196-38-9 is a valid CAS Registry Number.

Green Oxidation of Amines to Imines Based on the Development of Novel Catalytic Systems Using Molecular Oxygen or Hydrogen Peroxide

Marui, Kuniaki,Nomoto, Akihiro,Akashi, Haruo,Ogawa, Akiya

, p. 31 - 42 (2016)

Amines are transformed into the corresponding imines by environmentally benign catalytic oxidation reactions. Gaseous oxygen or hydrogen peroxide is used as the oxidant, and water is the only byproduct. When a vanadium complex is used as the catalyst in an ionic liquid, the amine oxidation successfully proceeds with recycling of the catalyst. Amine oxidation with hydrogen peroxide as an oxidant in water is also attained by using copper(II) sulfate as catalyst. In addition, photoinduced oxidation of amines to imines is conducted by using oxygen as the oxidant in the presence of a zinc-chlorin complex as catalyst.

Galactose Oxidase Variants for the Oxidation of Amino Alcohols in Enzyme Cascade Synthesis

Herter, Susanne,McKenna, Shane M.,Frazer, Andrew R.,Leimkühler, Silke,Carnell, Andrew J.,Turner, Nicholas J.

, p. 2313 - 2317 (2015)

The use of selected engineered galactose oxidase (GOase) variants for the oxidation of amino alcohols to aldehydes under mild conditions in aqueous systems is reported. GOase variant F2 catalyses the regioselective oxidation of N-carbobenzyloxy (Cbz)-protected 3-amino-1,2-propanediol to the corresponding α-hydroxyaldehyde which was then used in an aldolase reaction. Another variant, M3-5, was found to exhibit activity towards free and N-Cbz-protected aliphatic and aromatic amino alcohols allowing the synthesis of lactams such as 3,4-dihydronaphthalen-1(2H)-one, 2-pyrrolidone and valerolactam in one-pot tandem reactions with xanthine dehydrogenase (XDH) or aldehyde oxidase (PaoABC).

Visible-Light-Induced Controlled Oxidation of N-Substituted 1,2,3,4-Tetrahydroisoquinolines for the Synthesis of 3,4-Dihydroisoquinolin-1(2H)-ones and Isoquinolin-1(2H)-ones

Bansode, Ajay H.,Suryavanshi, Gurunath

, p. 1390 - 1400 (2021)

A visible light-rose bengal-TBHP mediated, controlled oxidation of N-substituted 1,2,3,4-tetrahydroisoquinolines is developed for the synthesis of 3,4-dihydroisoquinolin-1(2H)-ones and isoquinolin-1(2H)-ones. The present method feature's a broad substrate scope, good functional group tolerances, and the products were prepared in good to excellent yields. The developed methodology further demonstrated in the synthesis of isoindolo[2,1-b] isoquinolin-5(7H)-one (topoisomerase-I inhibitor). (Figure presented.).

INTRAMOLECULAR AMIDATION OF ARYLALKYLHYDROXAMIC ACIDS

Potapov, V.M.,Dem'yanovich, V. M.,Vendrova, O. E.,Khlebnikov, V. A.

, p. 528 - 533 (1983)

It is shown that mixtures of two isomeric benzolactams, viz., compounds of the benzamide and anilide type, are formed in the intramolecular amidation of arylalkylhydroxamic acids under the influence of polyphosphoric acid (PPA).A general reaction scheme that includes three pathways, viz., direct amidation, Losen rearrangement of the hydroxamic acids with subsequent cyclization of the isocyanates, and Beckmann rearrangement of the oximes of the cyclic ketones formed in the thermal cleavage of the starting hydroxamic acids in PPA, is proposed on the basis of a study of racemic and optically active arylalkylhydroxamic acids.

Synthesis of novel tricyclic aryltriazole-3-thione compounds

Cai, Cuiman,Plummer, Janet S.,Connor, David,Holsworth, Daniel D.,Edmunds, Jeremy J.

, p. 349 - 356 (2005)

A new synthetic protocol has been developed to provide entry into a series of novel tricyclic aryltriazole-3-thiones analogs. The classical reaction conditions of subjecting an arylhydrazide with thiophosgene to form the thioisocyanate intermediate and ultimately the corresponding aryltriazole-3-thione framework were not successful. However, using a combination of carbon disulfide and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to form the thioisocyanate intermediate was found to produce the novel tricyclic aryltriazole-3-thiones (5, 8a-c) in good yield.

Palladium-Catalyzed Carbonylation of β-Arylethylamide Directed by Oxalyl Amide in the Presence of Carbon Monoxide

Zhang, Li,Wang, Chao,Han, Jian,Huang, Zhi-Bin,Zhao, Yingsheng

, p. 5256 - 5262 (2016)

Pd-catalyzed regioselective coupling of β-C(sp2)-H bonds in aromatic amines protected by oxalyl amide with carbon monoxide is reported. The reaction could tolerate various functional groups and could afford good to excellent yields of the corresponding 3,4-dihydroisoquinolinone derivatives. Remarkably, it could also tolerate β-arylethylamino acid and thiopheneethylamine derivatives, thus showing their potential for producing several important units for bioactive compound synthesis.

Unusual dirhodium tetraacetate catalyzed intramolecular cyclization of isoquinoline diazoamides

Chelucci, Giorgio,Culeddu, Nicola,Saba, Antonio,Valenti, Raffaela

, p. 8269 - 8270 (1999)

The dirhodium(II) tetraacetate catalyzed decomposition of an isoquinoline diazoamide leads to the unexpected formation of a 1,3-oxazin-4-one ring which is consistent with a rare example of an intramolecular metal-carbene hydride-abstraction mechanism.

Clean and efficient benzylic C-H oxidation in water using a hypervalent iodine reagent: Activation of polymeric iodosobenzene with KBr in the presence of montmorillonite-K10

Dohi, Toshifumi,Takenaga, Naoko,Goto, Akihiro,Fujioka, Hiromichi,Kita, Yasuyuki

, p. 7365 - 7368 (2008)

(Chemical Equation Presented) We have found that unreactive and insoluble polymeric iodosobenzene [PhIO]n induced aqueous benzylic C-H oxidation to effectively give arylketones, in the presence of KBr and montmorillonite-K10 (M-K10) clay. Water-soluble and reactive species 1 having the unique I(III)-Br bond, in situ generated from [PhIO]n and KBr, was considered to be the key radical initiator during the reactions.

Selective oxidation of benzylic hydrocarbons to carbonyl compounds catalyzed by Mn(III) salen complexes

Lee, Nam Ho,Lee, Chang-Seob,Jung, Duk-Sang

, p. 1385 - 1388 (1998)

Selective oxidation of benzylic hydrocarbons to the carbonyl compounds was achieved using a racemic Mn(III) salen complex 1 as the catalyst. The reaction proceeds in good yields under mild reaction conditions using iodosobenzene or aq. sodium hypochlorite as a stoichiometric oxidant.

Visible-Light-Induced Oxidation of Diazenyl-Protected Tetrahydroisoquinolines and Isoindolines for the Synthesis of Functionalized Lactams

Jin, Weiwei,Liu, Chenjiang,Wang, Bin,Wang, Yanhong,Xia, Yu,Zhang, Tao,Zhang, Yonghong

, (2022/05/17)

A visible-light-induced oxidation of diazenyl-protected tetrahydroisoquinolines and isoindolines for the synthesis of structurally diverse lactams is developed. The reaction was carried out with Eosin Y-Na2 as an organic photocatalyst and molecular oxygen as an oxidant, and the desired functionalized N-aryldiazenyl-lactams were obtained under mild and transition metal-free conditions. The utility of this method is showcased by the gram-scale synthesis and deprotection of the N-aryldiazenyl-lactam product. (Figure presented.).
