23598-07-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23598-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,9 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23598-07:
(7*2)+(6*3)+(5*5)+(4*9)+(3*8)+(2*0)+(1*7)=124
124 % 10 = 4
So 23598-07-4 is a valid CAS Registry Number.

Coniferin dimerisation in lignan biosynthesis in flax cells

Beejmohun, Vickram,Fliniaux, Ophelie,Hano, Christophe,Pilard, Serge,Grand, Eric,Lesur, David,Cailleu, Dominique,Lamblin, Frederic,Laine, Eric,Kovensky, Jose,Fliniaux, Marc-Andre,Mesnard, Francois

, p. 2744 - 2752 (2007)

[13C2]-Coniferin was provided to a flax (Linum usitatissimum L.) cell suspension to monitor subsequent dimerisation by MS and NMR. The label was mainly incorporated into a 8-8′-linked lignan, lariciresinol diglucoside, a 8-5′-linked

Synthesis and purification of [1,2-13C2]coniferin

Beejmohun, Vickram,Grand, Eric,Lesur, David,Mesnard, Francois,Fliniaux, Marc-Andre,Kovensky, Jose

, p. 463 - 470 (2006)

The double labelled lignan precursors [1,2-13C 2]coniferin and the glucoside of [1,2-13C 2]ferulic acid were prepared by classical synthetic methods. Pure double labelled lignan precursors could only be obtained

SLAP reagents for the photocatalytic synthesis of C3/C5-substituted, N-unprotected selenomorpholines and 1,4-selenazepanes

Zhou, Guan,Deng, Xingwang,Pan, Chenyu,Goh, Eunice Tze Leng,Lakshminarayanan, Rajamani,Srinivasan, Rajavel

, p. 12546 - 12549 (2020/11/02)

Herein, we disclose the first set of unique selenium-containing SLAP (SiLicon Amine Protocol) reagents for the direct synthesis of C3/C5-substituted selenomorpholines and 1,4-selenazepanes fromdiverse (hetero)aldehydes under mild photocatalytic conditions. Enantiomerically pure 1,2-amino alcohol/α-amino acid versions of these heterocycles were also synthesized. Further, we have shown the late-stage modification of certain biologically active agents using the developed seleno-SLAPreagents.

Concise total synthesis of acylated phenolic glycosides vitexnegheteroin A and ovatoside D

Yan, Shiqiang,Ren, Sumei,Ding, Ning,Li, Yingxia

, p. 41 - 46 (2018/03/09)

Starting from readily available vanillin and α-D-acetobromo glucose, two natural acylated phenolic glycosides vitexnegheteroin A and ovatoside D were synthesized for the first time in 4 steps with overall yields of 54% and 65%, respectively. The key steps involve the directly regioselective O-6 acylation of vanillin β-D-glucopyranoside with acyl chlorides, and simultaneous removal of the allyl protecting groups on the phenolic acid moiety and reduction of the aldehyde in the aglycon moiety by using Pd(PPh)3-NaBH4 system in one pot.
