Abstract: Abstract Simple C2-symmetric chiral tertiary amines bearing squaramide fragments along with the 1,2-di(pyridin-2-yl)ethane spacer group have been synthesized. Among them, amine 8b with a different configuration of stereocenters in 1,2-di(pyridin-2-yl)ethane and 1,2-diaminocyclohexane units efficiently catalyzed… read more here.
