On May 21, 2010, Liu, Chen; Lu, Yixin published an article.HPLC of Formula: 167316-28-1 The title of the article was Primary amine/(+)-CSA salt-promoted organocatalytic conjugate addition of nitro esters to enones. And the article contained the following:
The combination of 9-amino-9-deoxy-epi-cinchonine and (+)-CSA resulted in a novel primary amine-based organocatalyst for effective iminium activation of 伪,尾-unsaturated ketones. Such a catalytic system could catalyze the conjugate addition of nitroacetate to enones in a highly enantioselective manner, affording the desired adducts in high yields and with up to 99% ee. The experimental process involved the reaction of N-[(1S,2S)-2-Amino-1,2-diphenylethyl]-1,1,1-trifluoromethanesulfonamide(cas: 167316-28-1).HPLC of Formula: 167316-28-1
