2-Methyl-4-phenylsulfonylamino-but-1-en is a complex organic chemical compound with the molecular formula C11H15NO2S. It features a but-1-en backbone, which is a four-carbon chain with a double bond between the first and second carbon atoms. One of the carbons in this chain is substituted with a methyl group (-CH3), and another is connected to a phenylsulfonylamino group. The phenylsulfonylamino group consists of a phenyl ring (C6H5) attached to a sulfonyl group (-SO2-), which in turn is connected to an amino group (-NH2). 2-Methyl-4-phenylsulfonylamino-but-1-en is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its role as an intermediate in organic synthesis. Due to its unique structure, it may exhibit specific chemical properties and reactivity patterns, making it a subject of interest in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 2080-61-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2080-61:
(6*2)+(5*0)+(4*8)+(3*0)+(2*6)+(1*1)=57
57 % 10 = 7
So 2080-61-7 is a valid CAS Registry Number.

A Radical-Initiated Fragmentary Rearrangement Cascade of Ene-Ynamides to [1,2]-Annulated Indoles via Site-Selective Cyclization

Li, Sifan,Wang, Yu,Wu, Zibo,Shi, Weiliang,Lei, Yibo,Davies, Paul W.,Shu, Wei

, p. 7209 - 7214 (2021/09/14)

Straightforward access to [1,2]-annulated indoles, key substructures in natural products, is highly desirable yet challenging. Herein, a radical triggered fragmentary cyclization cascade reaction of ene-ynamides is presented, providing a rapid access into [1,2]-annulated indoles by an intermolecular radical addition, intramolecular cyclization, desulfonylative aryl migration, and site-selective C(sp2)-N cyclization sequence. DFT calculations support oxidation of N-centered radical species to cations prior to the C-N bond formation, followed by an unusual aza-Nazarov cyclization.
