35498-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35498-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,9 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 35498-29:
(7*3)+(6*5)+(5*4)+(4*9)+(3*8)+(2*2)+(1*9)=144
144 % 10 = 4
So 35498-29-4 is a valid CAS Registry Number.

Cu-catalyzed cross-coupling of methyl ketones and pyridin-2-amines for the synthesis of N-(2-pyridyl)-α-ketoamides

Chen, Ali,Guo, Pengfeng,Lin, Haoming,Liu, Xiang,Rao, Chuixiong,Yang, Daji,Yu, Yue

, p. 417 - 421 (2020/11/30)

An efficient copper-catalyzed strategy for the synthesis of α-ketoamides via cross-coupling of methyl ketones and pyridin-2-amines is described. This transformation has provided a simple process for the formation of C?N and C=O bonds to prepare α-ketoamid

Direct Transformation of Alkylarenes into N-(Pyridine-2-yl)amides by C(sp3)–C(sp3) Bond Cleavage

Zhou, Haipin,Liu, Yanpeng,Xia, Haidong,Xu, Jinyi,Wang, Tingfang,Xu, Shengtao

, p. 6468 - 6473 (2020/10/02)

C(sp3)–H bond functionalization and C(sp3)–C(sp3) bond cleavage are very challenging transformations in chemistry. Herein, we report a mild and green methodology for the construction of N-(pyridine-2-yl)amides via tandem C(sp3)–H activation/C–C bond cleavage of alkylarenes. Various N-heterocyclic amides were directly synthesized from alkylarenes in water in moderate to good yields.

Diverse Oxidative C(sp2)-N Bond Cleavages of Aromatic Fused Imidazoles for Synthesis of α-Ketoamides and N-(pyridin-2-yl)arylamides

Xu, Fangzhou,Wang, Yanyan,Xun, Xiwei,Huang, Yun,Jin, Zhichao,Song, Baoan,Wu, Jian

, p. 8411 - 8422 (2019/05/17)

An efficient and chemoselective C(sp2)-N bond cleavage of aromatic imidazo[1,2-a]pyridine molecules is developed. A broad scope of amide compounds such as α-ketoamides and N-(pyridin-2-yl)arylamides are afforded as the final products in up to quantitative yields. Diverse C-N bond cleavages are controlled by the oxidative species used in this transformation, with various amide products afforded in a chemoselective fashion. A preliminary study indicated that some α-ketoamides exhibit anti-Tobacco Mosaic Virus activity for potential use in plant protection.
