25856-77-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25856-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,5 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25856-77:
(7*2)+(6*5)+(5*8)+(4*5)+(3*6)+(2*7)+(1*7)=143
143 % 10 = 3
So 25856-77-3 is a valid CAS Registry Number.

Ni-Catalyzed Carboxylation of Aziridines en Route to β-Amino Acids

Davies, Jacob,Janssen-Müller, Daniel,Zimin, Dmitry P.,Day, Craig S.,Yanagi, Tomoyuki,Elfert, Jonas,Martin, Ruben

supporting information, p. 4949 - 4954 (2021/04/07)

A Ni-catalyzed reductive carboxylation of N-substituted aziridines with CO2 at atmospheric pressure is disclosed. The protocol is characterized by its mild conditions, experimental ease, and exquisite chemo- and regioselectivity pattern, thus unlocking a new catalytic blueprint to access β-amino acids, important building blocks with considerable potential as peptidomimetics.

Carbon Isotope Labeling Strategy for β-Amino Acid Derivatives via Carbonylation of Azanickellacycles

Ravn, Anne K.,Vilstrup, Maria B. T.,Noerby, Peter,Nielsen, Dennis U.,Daasbjerg, Kim,Skrydstrup, Troels

supporting information, p. 11821 - 11826 (2019/08/16)

A series of 4-membered azametallacycles have been prepared by the oxidative addition of Ni(0) with aziridines. Stoichiometric 13C-labeled carbon monoxide could be efficiently incorporated via Ni-C bond insertion to generate air stable and isola

Synthesis of indolines: Via a palladium/norbornene-catalyzed reaction of aziridines with aryl iodides

Liu, Ce,Liang, Yujie,Zheng, Nian,Zhang, Bo-Sheng,Feng, Yuan,Bi, Siwei,Liang, Yong-Min

supporting information, p. 3407 - 3410 (2018/04/05)

A Pd- and norbornene-catalyzed domino procedure has been developed to synthesize indoline compounds. This reaction provides efficient access to indolines by employing aryl iodides with aziridines as new electrophiles. The transformation is scalable and tolerates a range of functional groups.
