Desmarchelier, Alaric,Yalgin, Hasret,Coeffard, Vincent,Moreau, Xavier,Greck, Christine
experimental part, p. 4430 - 4432 (2011/09/19)
Organocatalytic α-amination of α,α-disubstituted aldehydes promoted by 9-amino-(9-deoxy)-epi-quinine is described. α-Hydrazino aldehydes bearing a quaternary stereogenic center are obtained in good to excellent yields and enantioselectivities.

A novel ion pair catalyst containing a chiral counteranion can be readily derived by simply mixing cinchona alkaloid-derived diamine with chiral camphorsulfonic acid (CSA). A mixture of 9-amino(9-deoxy)epi-quinine 8 and (-)-CSA was found to be the best ca
