Calculate Digit Verification of CAS Registry Number 171868-16:
(8*1)+(7*7)+(6*1)+(5*8)+(4*6)+(3*8)+(2*1)+(1*6)=159
159 % 10 = 9

Asymmetric addition of diethylzinc to ketones promoted by tartaric acid derivatives

Hui, Ailing,Zhang, Jintang,Wang, Zhiyong

, p. 2374 - 2384 (2008/09/21)

The preparation of new sulfonamide ligands derived from L-tartaric acid and camphor sulfonyl chloride are described. The employment in the titanium tetraisopropoxide-promoted enantioselective addition of diethylzinc to ketones has been studied. The best enantiomeric excess is up to 99% with 7 mol% catalyst loading at room temperature. Copyright Taylor & Francis Group, LLC.
