Homochiral α-dibenzylamino aldehydes react with 4-butenylmagnesium bromide in diethyl ether at 0 °C to yield anti-β-amino alcohols in excellent yield and dr. These anti diastereoisomers were transformed into enantioenriched 2- and 2,6-substituted 3-piperidinols in good yields. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
同手性 α-二苄基氨基醛与 4-丁烯基溴化镁在乙醚中在 0 °C 下反应,以优异的产率和 dr. 产生抗 β-氨基醇。这些抗非对映异构体以良好的产率转化为富含对映体的 2- 和 2,6- 取代的 3-哌啶醇。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
