Check Digit Verification of cas no

The CAS Registry Mumber 833459-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,3,4,5 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 833459-47:
(8*8)+(7*3)+(6*3)+(5*4)+(4*5)+(3*9)+(2*4)+(1*7)=185
185 % 10 = 5
So 833459-47-5 is a valid CAS Registry Number.

Rhodium(iii)-catalyzed cascade C-H functionalization/annulation of sulfoximines with iodonium ylides for the synthesis of cyclohexanone-1,2-benzothiazines

Chen, Lu,Hao, Liqiang,Ji, Yafei,Wang, Yangyang,Wang, Zhichao,Wu, Gaorong,Xu, Xiaobo

supporting information, p. 887 - 894 (2022/02/03)

A highly efficient Rh(iii)-catalyzed cascade C-H activation/annulation of sulfoximines with iodonium ylides under metal-oxidant-free conditions has been reported. The fused cyclohexanone-1,2-benzothiazine scaffold is readily achieved with a one-pot proces

Electrochemical Oxidative Syntheses of NH-Sulfoximines, NH-Sulfonimidamides and Dibenzothiazines via Anodically Generated Hypervalent Iodine Intermediates

Kong, Xianqiang,Lin, Long,Chen, Xiaohui,Chen, Yiyi,Wang, Wei,Xu, Bo

, p. 3277 - 3282 (2021/07/26)

Herein, we report a general method for the synthesis of NH-sulfoximines and NH-sulfonimidamides through direct electrochemical oxidative catalysis involving an iodoarene(I)/iodoarene(III) redox couple. In addition, dibenzothiazines can be synthesized from [1,1′-biaryl]-2-sulfides under standard conditions. Notably, only a catalytic amount of iodoarene is required for the generation in situ of an active hypervalent iodine catalyst, which avoids the need for an excess of a hypervalent iodine reagent relative to conventional approaches. Moreover, this protocol features broad substrate scope and wide functional group tolerance, delivering the target compounds with good-to-excellent yields even for a scale of more than 10 g.

Preparation of S-2-halophenyl-2,1-benzothiazines

Garimalla, Aswin,Harmata, Michael

, (2021/03/15)

Derivatives of 2,1-benzothiazines are useful synthetic intermediates for a variety of applications. We became interested in developing a one-pot procedure to S-2-halophenyl-2,1-benzothiazines as potential precursors to P,N type ligands for metals. Accordingly, we reacted S-2-halophenyl-S-methylsulfoximines with 2-bromobenzaldehydes using the Buchwald-Hartwig reaction under conditions previously developed in our laboratory. We found that 2-halophenylmethyl sulfoximines show lower reactivity in process than methylphenyl sulfoximine. Among the 2-(S)-2-halophenyl-(S)-methylsulfoximines tested, S-2-fluorophenyl-S-methyl sulfoximine afforded higher yields of benzothiazines than the bromine- or chlorine-substituted congeners. In the coupling of S-2-halophenyl-S-methylsulfoximines to 2-bromobenzaldehyde, using Ruphos as a ligand gave the best yields.

Sulfoximines Assisted Rh(III)-Catalyzed C-H Activation/Annulation Cascade to Synthesize Highly Fused Indeno-1,2-benzothiazines

Li, Jian,Li, Hui,Fang, Daqing,Liu, Lingjun,Han, Xu,Sun, Jina,Li, Chunpu,Zhou, Yu,Ye, Deju,Liu, Hong

, p. 15217 - 15227 (2021/10/25)

A facile access to highly fused tetracyclic indeno-1,2-benzothiazines has been established via a Rh(III)-catalyzed C-H bond activation and intramolecular annulation cascade between sulfoximides and all-carbon diazo indandiones. This strategy is characterized by the fact that the diazo coupling partners do not require preactivation, along with its high efficiency, broad substrate generality, and facile transformation. Particularly, the highly conjugated tetracyclic products demonstrate good optical properties and can easily enter cells to emit bright fluorescence for live cell imaging.

Synthesis of NH-Sulfoximines by Using Recyclable Hypervalent Iodine(III) Reagents under Aqueous Micellar Conditions

Zhang, Guocai,Tan, Hongsheng,Chen, Weichun,Shen, Hong C.,Lu, Yue,Zheng, Changwu,Xu, Hongxi

, p. 922 - 928 (2020/02/20)

The synthesis of NH-sulfoximines from sulfides has been first developed under mild conditions in an aqueous solution with surfactant TPGS-750-M as the catalyst at room temperature. In this newly developed process, a simple and convenient recycling strategy to regenerate the indispensable hypervalent iodine(III) is used. The resulting 1,2,3-trifluoro-5-iodobezene can be recovered almost quantitively from the mixture by liquid–liquid extraction and then oxidized to give the corresponding iodine(III) species. This optimized procedure is compatible with a broad range of functional groups and can be easily performed on a gram scale, providing a green protocol for the synthesis of sulfoximines.

Sulfoximines-assisted Rh(III)-catalyzed C-H activation and intramolecular annulation for the synthesis of fused isochromeno-1,2-benzothiazines scaffolds under room temperature

Han, Xu,Li, Chunpu,Li, Jian,Liu, Hong,Wang, Bao

, (2020/06/29)

Amild and facile Cp?Rh(III)-catalyzed C-Hactivation and intramolecular cascade annulation protocol has been proposed for the furnishing of highly fused isochromeno-1,2-benzothiazines scaffolds using S-phenylsulfoximides and 4-diazoisochroman-3-imine as substrates under room temperature. This method features diverse substituents and functional groups tolerance and relatively mild reaction conditions with moderate to excellent yields. Additionally, retentive configuration of sulfoximides in the conversion has been verified.

Efficient Kinetic Resolution of Sulfur-Stereogenic Sulfoximines by Exploiting CpXRhIII-Catalyzed C?H Functionalization

Brauns, Marcus,Cramer, Nicolai

supporting information, p. 8902 - 8906 (2019/06/04)

Chiral sulfoximines with stereogenic sulfur atoms are promising motifs in drug discovery. We report an efficient method to access chiral sulfoximines through a C?H functionalization based kinetic resolution. A rhodium(III) complex equipped with a chiral Cpx ligand selectively participates in conjunction with phthaloyl phenylalanine in the C?H activation of just one of the two sulfoximine enantiomers. The intermediate reacts with various diazo compounds, providing access to chiral 1,2-benzothiazines with synthetically valuable substitution patterns. Both sulfoximines and 1,2-benzothiazines were obtained in high yields and excellent enantioselectivity, with s-values of up to 200. The utility of the method is illustrated by the synthesis of the key intermediates of two pharmacologically relevant kinase inhibitors.

Copper-catalyzed oxidative decarboxylative coupling of α-keto acids and sulfoximines

Pimpasri, Chaleena,Sumunnee, Ladawan,Yotphan, Sirilata

supporting information, p. 4320 - 4327 (2017/07/10)

A copper-catalyzed oxidative decarboxylative coupling of α-keto acids with NH-sulfoximines has been developed. With CuBr as the catalyst and K2S2O8 as the oxidant, this reaction enables the formation of a C-N bond and gives N-aroylsulfoximine products in moderate to excellent yields. The reaction mechanism is likely to involve the generation of a reactive aroyl radical intermediate.
