130284-35-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130284-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,8 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130284-35:
(8*1)+(7*3)+(6*0)+(5*2)+(4*8)+(3*4)+(2*3)+(1*5)=94
94 % 10 = 4
So 130284-35-4 is a valid CAS Registry Number.

Carbometalations of simple alkenes with allyldibromoborane.

Frantz,Singleton

, p. 485 - 486 (1999)

[formula: see text] The allylboration of alkenes with allyldibromoborane is described. Utilizing an improved methodology for the synthesis of allyldibromoborane, 1,3-dienes, styrene, and even isolated alkenes could be carbometalated in high yield regio- a

syn-Selective Michael Reaction of α-Branched Aryl Acetaldehydes with Nitroolefins Promoted by Squaric Amino Acid Derived Bifunctional Br?nsted Bases

Campano, Teresa E.,García-Urricelqui, Ane,Mielgo, Antonia,Palomo, Claudio,de Cózar, Abel

supporting information, p. 3604 - 3612 (2021/07/26)

Here we describe a direct access to 2,2,3-trisubstituted syn γ-nitroaldehydes by addition of α-branched aryl acetaldehydes to nitroolefins promoted by a cinchona based squaric acid-derived amino acid peptide. Different α-methyl arylacetaldehydes react with β-aromatic and β-alkyl nitroolefins to afford the Michael adducts in high enantioselectivity and syn-selectivity. NMR experiments and DFT calculations predict the reaction to occur through the intermediacy of E-enolate. The interaction between the substrates and the catalyst follows Pápai's model, wherein an intramolecular H-bond interaction in the catalyst between the NH group of one of the tert-leucines and the squaramide oxygen seems to be key for discrimination of the corresponding reaction transition states.

Highly Enantioselective Catalytic Kinetic Resolution of α-Branched Aldehydes through Formal Cycloaddition with Homophthalic Anhydrides

Farid, Umar,Aiello, Maria Luisa,Connon, Stephen J.

supporting information, p. 10074 - 10079 (2019/07/18)

A new catalytic methodology was developed to promote an efficient one-pot kinetic resolution of racemic aldehydes with selectivity (s*) of up to 91 (99:1 d.r., >99 % ee) in a cycloaddition reaction with enolizable anhydrides to afford dihydroisocoumarin products (a core prevalent in natural products and molecules of medicinal interest) containing three contiguous stereocentres.
