35943-98-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35943-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,9,4 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 35943-98:
(7*3)+(6*5)+(5*9)+(4*4)+(3*3)+(2*9)+(1*8)=147
147 % 10 = 7
So 35943-98-7 is a valid CAS Registry Number.

Applicability of aluminum amalgam to the reduction of arylnitro groups

Luzzio, Frederick A.,Monsen, Paige J.

supporting information, (2020/11/02)

An array of arylnitro compounds with various functionality were treated with freshly-prepared aluminum amalgam in THF/water solution and resulted in the corresponding arylamines. The Al(Hg)-mediated reductions are relatively rapid with consumption of the amalgam and disappearance of starting material occurring over 20–30 min. The workup of the reductions involves only removal of the insoluble by-products by filtration followed by concentration. Only in some cases is chromatography required to secure the pure product. The desired arylamines are furnished in quantities of 25–100 mg, which in some cases, could be taken on to the next reaction without further purification. Reductions of 4-nitrobenzyl derivatives of carbohydrates or nucleosides were selective in affording the corresponding 4-aminobenzyl products. To show applicability in click chemistry, selected aminobenzyl products are directly azidated to yield products that were then used in click reactions to afford the corresponding 1,2,3-triazoles.

Direct N-H/ N-Me Aziridination of Unactivated Olefins Using O-(Sulfonyl)hydroxylamines as Aminating Agents

Sabir, Shekh,Pandey, Chandra Bhan,Yadav, Ajay K.,Tiwari, Bhoopendra,Jat, Jawahar L.

, p. 12255 - 12260 (2018/09/27)

Unactivated aziridines are the core substructures in a plethora of bioactive natural products and serve as building blocks in organic synthesis. Despite this, very limited methods are available to access them directly from olefins, as most of the known me

Enantioselective total synthesis of (-)-walsucochin B

Xu, Shiyan,Gu, Jixiang,Li, Huilin,Ma, Donghui,Xie, Xingang,She, Xuegong

supporting information, p. 1996 - 1999 (2014/05/06)

The first enantioselective total synthesis of the structurally unique nortriterpenoid (-)-walsucochin B has been accomplished through the cationic polyolefin cyclization initiated by chiral epoxide. The core framework and the stereocenters in the natural
