Uses

Cyclopropanesulfonyl chloride can be used in the synthesis of (1R,2S)-1-amino-2-vinylcyclopropanecarboxylic sulfonamide derivatives, which can serve as building blocks in the preparation of potent hepatitis C virus NS3 protease inhibitors.

Check Digit Verification of cas no

The CAS Registry Mumber 139631-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,3 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139631-62:
(8*1)+(7*3)+(6*9)+(5*6)+(4*3)+(3*1)+(2*6)+(1*2)=142
142 % 10 = 2
So 139631-62-2 is a valid CAS Registry Number.

Copper-Catalyzed N-Directed Distal C(sp3)-H Sulfonylation and Thiolation with Sulfinate Salts

Chen, Guang-Le,He, Shi-Hui,Cheng, Liang,Liu, Feng

supporting information, p. 8338 - 8342 (2021/10/25)

We herein report a selective and catalytic C(sp3)-H functionalization approach to access amines bearing organo-sulfonyl and organo-thiol groups. This reaction proceeds through a cascade process of N-radical formation, alkyl radical formation via 1,5-HAT, and C-S bond formation, thereby offering a series of functionalized amines. This method could enable primary, secondary, and tertiary C(sp3)-H sulfonylation and thiolation and also exhibits good functional group tolerance.

Selective Late-Stage Sulfonyl Chloride Formation from Sulfonamides Enabled by Pyry-BF4

Gómez-Palomino, Alejandro,Cornella, Josep

supporting information, p. 18235 - 18239 (2019/11/13)

Reported here is a simple and practical functionalization of primary sulfonamides, by means of a pyrylium salt (Pyry-BF4), with nucleophiles. This simple reagent activates the poorly nucleophilic NH2 group in a sulfonamide, enabling the formation of one of the best electrophiles in organic synthesis: a sulfonyl chloride. Because of the variety of primary sulfonamides in pharmaceutical contexts, special attention has been focused on the direct conversion of densely functionalized primary sulfonamides by a late-stage formation of the corresponding sulfonyl chloride. A variety of nucleophiles could be engaged in this transformation, thus permitting the synthesis of complex sulfonamides, sulfonates, sulfides, sulfonyl fluorides, and sulfonic acids. The mild reaction conditions and the high selectivity of Pyry-BF4 towards NH2 groups permit the formation of sulfonyl chlorides in a late-stage fashion, tolerating a preponderance of sensitive functionalities.
