A new strategy for enantioselective synthesis of azacyclic molecules in which dynamickinetic equilibration of diastereomeric iminium ions precedes a stereochemistry-determining sigmatropic rearrangement is reported. The method is illustrated by the synthesis, in high enantiomeric purity (generally 95–99% ee), of a variety of 1-azabicyclic molecules containing angular allyl or 3-substituted 2-propenyl
