6´-Aminocinchonine Base – Fine Chemical

CAS-No. 2143936-31-4

6´-Aminocinchonine Base (CAS-No. 2143936-31-4) belongs to a new class of Cinchona alkaloids, bearing a free amio group in the C6’-position. Despite its position far away from the stereocenters, the amino group proves crucial to obtain high enantioselectivity in synthetically relevant reactions like Michael additions etc..
On the other hand the free C6’ amino group can be further functionalized to improve catalytic performance. A wide range of completely new chiral ligands and catalysts are easily accessible.
