摘要：

Using a chiral base from a norephedrine-derived diamine, the enantioselective rearrangement of a mesocyclohexene oxide can be performed in 94% yield and with 94% enantioselectivity. The enantioselectivity is lower (86% ee) with the diastereoisomeric chiral base. In order to prepare the diastereoisomeric chiral base, a potentially useful way of converting norephedrine into norpseudophedrine was developed. (C) 1999 Elsevier Science Ltd. All rights reserved.
