Check Digit Verification of cas no

The CAS Registry Mumber 260997-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,9,9 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 260997-38:
(8*2)+(7*6)+(6*0)+(5*9)+(4*9)+(3*7)+(2*3)+(1*8)=174
174 % 10 = 4
So 260997-38-4 is a valid CAS Registry Number.

The Generation of Difluoroketenimine and Its Application in the Synthesis of α,α-Difluoro-β-amino Amides

Zhang, Rui,Zhang, Zhikun,Zhou, Qi,Yu, Lefei,Wang, Jianbo

supporting information, p. 5744 - 5748 (2019/03/28)

Fluorine-containing β-amino acids and their derivatives have attracted significant attention due to their importance in life sciences. Herein the previously unknown difluoroketenimine, the analogue of the elusive difluoroketene, has been generated by the

Visible-light, iodine-promoted formation of n-sulfonyl imines and n-alkylsulfonamides from aldehydes and hypervalent iodine reagents

Alternative synthetic methodology for the direct installation of sulfonamide functionality is a highly desirable goal within the domain of drug discovery and development. The formation of synthetically valuable N-sulfonyl imines from a range of aldehydes,

Formation of: N -sulfonyl imines from iminoiodinanes by iodine-promoted, N-centered radical sulfonamidation of aldehydes

Hopkins, Megan D.,Scott, Kristina A.,Demier, Brettany C.,Morgan, Heather R.,Macgruder, Jesse A.,Lamar, Angus A.

, p. 9209 - 9216 (2017/11/14)

A mild and operationally convenient formation of synthetically valuable N-sulfonyl imines from a range of aryl aldehydes by reaction with iminoiodinanes (PhINZ) and I2 has been developed. According to mechanistic experiments described within, the reaction is speculated to proceed through an unconventional light-promoted, N-centered radical (NCR) pathway involving a N,N-diiodosulfonamide reactive species. This method not only provides a new pathway toward the production of activated imines, but also serves as an example of a non-traditional means of carbonyl activation via an NCR species.

Highly Enantioselective Ferrocenyl Palladacycle-Acetate Catalysed Arylation of Aldimines and Ketimines with Arylboroxines

Schrapel, Carmen,Frey, Wolfgang,Garnier, Delphine,Peters, René

supporting information, p. 2448 - 2460 (2017/02/23)

Benzylic N-substituted stereocenters constitute a frequent structural motif in drugs. Their highly enantioselective generation is hence of technical importance. An attractive strategy is the arylation of imines with organoboron reagents. Chiral Rh complexes have reached a high level of productivity for this reaction type. In this article we describe that an electron rich PdIIcatalyst also performs well in the arylation of aldimines, comparable to the best Rh catalysts. The ferrocenyl palladacycle-acetate catalyst allows for a broad substrate scope and very high enantioselectivities. Commonly observed side reactions like aryl–aryl homocouplings and imine hydrolysis could be blocked. Mechanistic studies implicate that a) the acetate ligand is crucial for transmetallation, b) the active catalyst is most likely a palladacycle-OAc monomer, c) the rate limiting step is probably the product release. By added KOAc the arylation could also be applied to ketimines.

Exogenous-Base-Free Palladacycle-Catalyzed Highly Enantioselective Arylation of Imines with Arylboroxines

Schrapel, Carmen,Peters, Ren

supporting information, p. 10289 - 10293 (2015/09/01)

Enantiomerically pure benzylic amines are important for the development of new drugs. A readily accessible planar-chiral ferrocene-derived palladacycle is shown to be a highly efficient catalyst for the formation of N-substituted benzylic stereocenters; t

Cycloadditions of N-sulfonyl nitrones generated by Lewis acid catalyzed rearrangement of oxaziridines

We have developed cycloaddition reactions of novel, electron-deficient N-nosyl nitrones that arise from the titanium(IV)-catalyzed rearrangement of the corresponding N-nosyl oxaziridines. A diverse range of styrenes and oxaziridines react smoothly in this
