93086-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93086-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,8 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93086-29:
(7*9)+(6*3)+(5*0)+(4*8)+(3*6)+(2*2)+(1*9)=144
144 % 10 = 4
So 93086-29-4 is a valid CAS Registry Number.

Combining organocatalysis with photoorganocatalysis: photocatalytic hydroacylation of asymmetric organocatalytic Michael addition products

Schiza, Andriana,Spiliopoulou, Nikoleta,Shahu, Adelajda,Kokotos, Christoforos G.

supporting information, p. 18844 - 18849 (2018/11/26)

Organocatalysis and photoorganocatalysis are two areas of synthetic methodology that have found wide applications in organic synthesis. Herein, we report a combination of these two stategies, taking advantage of an organocatalytic Michael addition of α,α-disubstituted aldehydes to maleimides as the first step and a photocatalytic hydroacylation of diisopropyl azodicarboxylate as the second step. Employing an amino acid as the organocatalyst for the asymmetric organocatalytic part and an organic molecule as the photocatalyst, the combination of these two strategies led to the desired products. A number of alkyl- and aryl-substituted maleimides were successfully employed, while the protocol can be used on α,α-disubstituted aldehydes leading to products in moderate to high yields (44-84%) and excellent enantioselectivities (98-100% ee).

Importance of N-terminal proline for the promiscuous activity of 4-oxalocrotonate tautomerase (4-OT)

Lazic, Jelena,Spasic, Jelena,Francuski, Djordje,Tokic-Vujosevic, Zorana,Nikodinovic-Runic, Jasmina,Maslak, Veselin,Djokic, Lidija

, p. 871 - 881 (2016/10/06)

Michael addition of aldehydes to nitro-olefins is an effective method to obtain useful chiral γ-nitroaldehydes. γ-Nitroaldehydes are precursors for chiral γ-aminobutyric acid analogues, which have numerous pharmacological activities and are used for the treatment of neurological disorders. A whole-cell system based on recombinantly expressed 4-oxalocrotonate tautomerase (4-OT) was developed and shown to be an effective biocatalyst for the Michael addition of branched aldehydes to β-nitrostyrenes. The aim of this study was to investigate the influence of the substitution of the N-terminal proline with lysine and arginine, both containing a reactive ε-amino group, on the Michael addition catalyzed by 4-OT. First, the effects of these mutations were examined by in silico analysis, followed by the generation of three terminal lysine mutants. The generated mutants, 4-OT-K, 4-OT-PK and 4-OT-KK were tested for their ability to utilise β-nitrostyrene (1), (E)-1-nitro-2-(2-thienyl)ethene (2) and trans-p-chloro-β-nitrostyrene (3) as Michael acceptors with isobutanal (2-methylpropanal) as the donor. For comparison, the lithium salt of lysine was used in the same organocatalytic reactions. In general, the introduction of lysine had a negative effect on Michael additions based on overall product yields. However, additional lysine residues at the N-terminus of the protein resulted in structural changes that enhanced the activity towards 2 and 3. Therefore, the N-terminal proline is important for 4-OT-catalysed Michael-additions, but it is not essential.
