1350897-04-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1350897-04-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,0,8,9 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1350897-04:
(9*1)+(8*3)+(7*5)+(6*0)+(5*8)+(4*9)+(3*7)+(2*0)+(1*4)=169
169 % 10 = 9
So 1350897-04-9 is a valid CAS Registry Number.

Asymmetric Michael addition organocatalyzed by α,β-dipeptides under solvent-free reaction conditions

Avila-Ortiz, C. Gabriela,Lenin, Diaz-Corona,Erika, Jiménez-González,Juaristi, Eusebio

, (2017)

The application of six novel α,β-dipeptides as chiral organocatalysts in the asymmetric Michael addition reaction between enolizable aldehydes and N-arylmaleimides or nitroolefins is described. With N-arylmaleimides as substrates, the best results were achieved with dipeptide 2 as a catalyst in the presence of aq. NaOH. Whereas dipeptides 4 and 6 in conjunction with 4-dimethylaminopyridine (DMAP) and thiourea as a hydrogen bond donor proved to be highly efficient organocatalytic systems in the enantioselective reaction between isobutyraldehyde and various nitroolefins.

Organocatalytic enantioselective conjugate addition of aldehydes to maleimides in deep eutectic solvents

Flores-Ferrándiz, Jesús,Chinchilla, Rafael

, p. 302 - 306 (2017/02/18)

The conjugate enantioselective addition of aldehydes, mainly α,α-disubstituted, to maleimides leading to enantioenriched succinimides, has been achieved in recyclable deep eutectic solvents at room temperature. Enantiomerically pure carbamate-monoprotecte

Stereoselective conjugate addition of carbonyl compounds to maleimides using a diaminomethyleneindenedione organocatalyst

Nakashima, Kosuke,Kawada, Masahiro,Hirashima, Shin-ichi,Kosugi, Ayako,Kato, Mana,Yoshida, Akihiro,Koseki, Yuji,Miura, Tsuyoshi

, p. 888 - 895 (2016/09/02)

A diaminomethyleneindenedione motif can serve as an excellent double hydrogen bonding donor. Bifunctional chiral primary amine 3 bearing a diaminomethyleneindenedione motif is an excellent organocatalyst to promote the asymmetric conjugate additions of va

Solvent-induced reversal of enantioselectivity in the synthesis of succinimides by the addition of aldehydes to maleimides catalysed by carbamate-monoprotected 1,2-diamines

Flores-Ferrndiz, Jess,Fiser, Bla,Gmez-Bengoa, Enrique,Chinchilla, Rafael

, p. 1218 - 1225 (2015/03/04)

A simple change in the polarity of the solvent allows both enantiomers of substituted succinimides to be obtained in the enantioselective conjugate addition reaction of aldehydes, mainly disubstituted, to maleimides catalysed by chiral carbamate-monoprote

Solvent-dependent enantioswitching in the Michael addition of α,α-disubstituted aldehydes to maleimides organocatalyzed by mono-N-Boc-protected cyclohexa-1,2-diamines

Flores-Ferrándiz, Jesús,Chinchilla, Rafael

, p. 1091 - 1094 (2014/10/15)

Enantiomerically pure mono-N-Boc-protected trans-cyclohexa-1,2-diamines are used as organocatalysts for the enantioselective conjugate addition of α,α-disubstituted aldehydes to maleimides. Using a single enantiomer of the organocatalyst, both enantiomeri

An asymmetric Michael addition of α,α-disubstituted aldehydes to maleimides leading to a one-pot enantioselective synthesis of lactones catalyzed by amino acids

supporting information, p. 2406 - 2409 (2013/06/27)

A cheap and fast construction of both enantiomers of substituted succinimides is reported. α- or β-amino acids, such as β-phenylalanine and α-tert-butyl aspartate, were found to be efficient organocatalysts for the reaction between α,α-disubstituted aldeh

Calixarene-based chiral primary amine thiourea promoted highly enantioselective asymmetric Michael reactions of α,α-disubstituted aldehydes with maleimides

Durmaz, Mustafa,Sirit, Abdulkadir

, p. 1443 - 1448 (2013/12/04)

Calix[4]arene based chiral bifunctional thiourea-primary amines have been shown to act as effective catalysts for the Michael addition of aldehydes to maleimides for the first time. The corresponding adducts were generally obtained preferentially in (R)-

Enantioselective Michael addition of aldehydes to maleimides organocatalysed by chiral 1,2-diamines: An experimental and theoretical study

Avila, Angel,Chinchilla, Rafael,Gomez-Bengoa, Enrique,Najera, Carmen

, p. 1531 - 1535 (2013/12/04)

Simple and commercially available chiral 1,2-diamines were used as organocatalysts for the enantioselective conjugate addition of aldehydes, including α,α-disubstituted, to maleimides. The reaction was carried out in the presence of hexanedioic acid as an

Enantioselective Michael addition of α,α-disubstituted aldehydes to maleimides organocatalyzed by chiral primary amine-guanidines
