Synthesis of new enantiopure aminodiols and their use as ligands for the addition of diethylzinc to benzaldehyde
摘要:
The synthesis of new enantiopure aminodiols through aminolytic ring opening of chiral epoxy alcohols derived from (+)-camphor and (-)-fenchone is described. The absolute configurations were determined by NMR methods. The aminodiols catalyzed the addition of diethylzinc to benzaldehyde in high yields and with enantioselectivities of up to 80%.
