439271-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 439271-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,2,7 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 439271-80:
(8*4)+(7*3)+(6*9)+(5*2)+(4*7)+(3*1)+(2*8)+(1*0)=164
164 % 10 = 4
So 439271-80-4 is a valid CAS Registry Number.

Development of chiral catalysts by asymmetric activation for highly enantioselective diethylzinc addition to imines

Zhang, Hai-Le,Liu, Hua,Cui, Xin,Mi, Ai-Qiao,Jiang, Yao-Zhong,Gong, Liu-Zhu

, p. 615 - 618 (2005)

Based on the asymmetric activation concept, a library of chiral zinc complexes in situ formed by the combination of diimines derived from chiral 1,2-diphenyl-ethanene-1,2-diamine, BINOL derivatives, and diethylzinc are evaluated in the asymmetric addition of diethylzinc to N-acylimines. In the presence of 10 mol% L3ZnA1, high enantioselectivities and yields were provided for a wide range of aromatic imines in 1,2-dichloroethane at -25 °C.

Discovery of chiral catalysts by asymmetric activation for highly enantioselective diethylzinc addition to imines: Using racemic and achiral diimines as effective activators

Liu, Hua,Zhang, Hai-Le,Wang, Shuang-Jun,Mi, Ai-Qiao,Jiang, Yao-Zhong,Gong, Liu-Zhu

, p. 2901 - 2907 (2007/10/03)

A library of chiral zinc complexes formed in situ by the combination of achiral and racemic diimines with 3,3′-di(3,5-ditrifluoromethylphenyl)- BINOL and diethylzinc were evaluated in the asymmetric addition of diethylzinc to N-acylimines. In the presence of 10 mol % of chiral ligand 4 and racemic diimine 5, high enantioselectivities of up to 97% ee and yields of up to 96% were achieved for a wide range of aromatic imines in dichloromethane at -30°C.
