Abstract
Preparation of N-alkylated 2-epi-valienamines was accomplished by the palla dium-catalyzed coupling reaction of the allylic chloride 5 with various ami nes in the presence of trimethylolpropane phosphite (TMPP). The 2-epi-valie namine precursor (i.e, allylic chloride 5) was obtained from the reaction o f diol 2 with Viehe's salt and the diol 2 was readily prepared from (-)-qui nic acid in 10 steps.
