important intermediates in organic synthesis and flavor compounds in food chemistry, were synthesized by deprotonation of N-(1-alkoxy-2-propylidene)isopropylamine, prepared by condensation of the corresponding α-alkoxyacetone with isopropylamine, and subsequent reaction of the corresponding 1-azaallylic anions with alkyl halides to afford α′-alkylated, α-alkylated and α,α′-dialkylated ketimines.

The efficient intermolecular alkoxylation reactions of various enolacetates and different alcohols are developed in the electrochemical process for the first time. Enolacetatesderivedfrom either aromatic, alkyl, or alicyclic ketones, and abundant free alcohols directly used in this synthetic strategy, make this transformation very valuable in synthesis and application in the future.
