专利号:WO-9950216-A1 优先权日:1998-03-31 标 题 :Novel chiral inducers, preparation method, use in asymmetrical synthesis and resulting products 发明人:DUHAMEL PIERRE; DUHAMEL LUCETTE; MEYER LUC; POIRIER JEAN-MARIE 权利人:CENTRE NAT RECH SCIENT 摘要:The invention concerns novel chiral inducers of formula (I) wherein Y is selected among a hydrogen atom, an alkyl radical, a hydroxyl function, a -O-SiR'3 radical, a -SR' radical, or a -NR'2 radical, where R' is an alkyl radical, n is 0 or 1, and R is selected among an alkyl radical, an aryl radical, a SR' radical, or an OR' radical. The invention also concerns a method for obtaining said chiral inducers, their use in asymmetric synthesis and the resulting synthesised products. Said chiral inducers can be used in particular in synthesis processes of chiral alpha-substituted amines.
