Asymmetric synthesis of vicinal amino alcohols via organocatalytic sequential α-amination/Grignard addition reactions of aldehydes
摘要:
An organocatalytic sequential alpha-amination/Grignard addition reaction of aliphatic aldehydes is reported. The synthetically useful anti-vicinal amino alcohol derivatives were obtained in high yields and with high stereoselectivities. These derivatives could be easily transformed into oxazolidinones.

alpha,alpha-Bis[bis-3,5-(trifluoromethyl)phenyl]prolinol silyl ether anchored onto polystyrene was synthesized and tested in asymmetric alpha-amination of aldehydes. The catalytic activity and enantioselectivity of the immobilized catalyst persist for 3 cycles.
