831192-69-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 831192-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,1,1,9 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 831192-69:
(8*8)+(7*3)+(6*1)+(5*1)+(4*9)+(3*2)+(2*6)+(1*9)=159
159 % 10 = 9
So 831192-69-9 is a valid CAS Registry Number.

Homoallylic amines as efficient chiral inducing frameworks in the conjugate addition of amides to α,β-unsaturated esters. An entry to enantio-enriched diversely substituted amines

Anani, Lilia,Behr, Jean-Bernard,Coelho, Aurélien,Machado-Rodrigues, Carine,Massicot, Fabien,Rogier, Johann,Vasse, Jean-Luc

supporting information, p. 2632 - 2636 (2020/04/17)

The diastereoselective conjugate addition of secondary homoallylamines, obtained in the enantioenriched form via allylmetallation of imines, to α,β-unsaturated esters is reported. This method allows access to valuable building blocks as well as heterocyclic skeletons, providing tertiary amines bearing two chains integrating a stereogenic center adjacent to the nitrogen atom.

Adducts of Triallylborane with Ammonia and Aliphatic Amines as Stoichiometric Allylating Agents for Aminoallylation Reaction of Carbonyl Compounds

Kuznetsov, Nikolai Yu.,Tikhov, Rabdan M.,Strelkova, Tatiana V.,Bubnov, Yuri N.

supporting information, p. 3549 - 3552 (2018/06/26)

Triallylborane-amines adducts are effective stoichiometric allylating agents in the aminoallylation reaction of carbonyl compounds in methanol. Moreover, copper-catalyzed diastereoselective allylation of Ellman's imine was achieved with triallylborane-methylamine adduct.

2,2- and 2,6-diarylpiperidines by aryl migration within lithiated urea derivatives of tetrahydropyridines

Tait, Michael B.,Butterworth, Sam,Clayden, Jonathan

supporting information, p. 1236 - 1239 (2015/03/14)

2-Aryltetrahydropyridines formed by anionic cyclization or ring-closing metathesis were converted to their N′-aryl urea derivatives. Depending on the position of the unsaturation within the tetrahydropyridine ring, metalation by deprotonative lithiation or carbolithiation led to migration of the N′-aryl substituent to the 2- or 6-position via intramolecular nucleophilic attack of a benzylic organolithium on the aryl ring. The products are a range of 2,2-, 2,2,3-, and 2,6-polysubstituted piperidine derivatives. Related chemistry was observed in pyrroline homologues.
