“Asymmetric Electrophilic α-Amidoalkylation” reactions with a chiral alkylaminocarbonyl unit as chiralauxiliary are used for the stereoselectivesynthesis of 2-substituted piperidinederivatives. Intramolecular condensation of the nitrogen of the aminocarbonyl group with the keto function present in the newly introduced side chain of the amidoalkylation products results in the formation of hexahydropyrido[1
