Check Digit Verification of cas no

The CAS Registry Mumber 93098-26-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,9 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93098-26:
(7*9)+(6*3)+(5*0)+(4*9)+(3*8)+(2*2)+(1*6)=151
151 % 10 = 1
So 93098-26-1 is a valid CAS Registry Number.

Diastereoselective construction of spirocyclic pyrrolidines bearing two quaternary centers via CuII-P, N-Ligand catalyzed 1,3-dipolar cycloaddition

Tang, Li-Wei,Li, Chuan,Zhao, Bao-Jing,Lan, Li,Zhang, Man,Zhou, Zhi-Ming

, p. 923 - 930 (2017)

Here, we report a convenient access to diastereoselective synthesis of polysubstituted pyrrolidines bearing a unique spiro quaternary center at the C-2 position and another quaternary center at C-4. The synthesis system, CuII/P, N-Ligand-cataly

Unnatural α-amino ethyl esters from diethyl malonate or ethyl β-bromo-α-hydroxyiminocarboxylate

Coutant, Eloi P.,Hervin, Vincent,Gagnot, Glwadys,Ford, Candice,Baatallah, Racha,Janin, Yves L.

supporting information, p. 2853 - 2860 (2018/11/26)

We have explored here the scope of the age-old diethyl malonate-based accesses to α-amino esters involving Knoevenagel condensations of diethyl malonate on aldehydes, reductions of the resulting alkylidenemalonates, the preparation of the corresponding α-hydroxyimino esters and their final reduction. This synthetic pathway turned out to be general although some unexpected limitations were encountered. The synthetic modifications of some of the intermediates - using Suzuki-Miyaura coupling or cycloadditions - before undertaking the oximation step - provided accesses to further α-amino esters. Moreover, other pathways to α-hydroxyimino esters were explored including an attempt to improve the cycloadditions between ethyl β-bromo-α-hydroxyiminocarboxylate and various alkylfuranes.

Chiral-Zn(NTf2)2-complex-catalyzed diastereo- and enantioselective direct conjugate addition of arylacetonitriles to alkylidene malonates

Yao, Jingjing,Liu, Xiaohua,He, Peng,Zhu, Yin,Lian, Xiangjin,Lin, Lili,Feng, Xiaoming

supporting information, p. 16424 - 16430 (2013/12/04)

Chiral N,N′-dioxide/Zn(NTf2)2 complexes were demonstrated to be highly effective in the direct asymmetric conjugate addition of arylacetonitriles to alkylidene malonates under mild conditions. A wide range of substrates were tolerated to afford their corresponding products in moderate-to-good yields with high diastereoselectivities (82:18->99:1 d.r.) and enantioselectivities (81-99 % ee). The reactions performed well, owing to the high Lewis acidity of the metal triflimidate and a ligand-acceleration effect. The N,N′-dioxide also benefited the deprotonation process as a Bronsted base. The catalytic reaction could be performed on the gram-scale with retention of yield, diastereoselectivity, and enantioselectivity. The products that contained functional groups were ready for further manipulation. In addition, a possible catalytic model was proposed to explain the origin of the asymmetric induction. Copyright
