Rapid access to enantiopure bupropion and its major metabolite by stereospecific nucleophilic substitution on an α-ketotriflate
摘要:
A stereospecific method for the synthesis of enantiopure alpha -aminoketone from its corresponding alpha -hydroxy-ketone via the triflate intermediate is discussed. This strategy provides a rapid and efficient route for the preparation of either enantiomer of bupropion and its biologically active hydroxylated metabolite, (C) 2000 Elsevier Science Ltd.
