A simple and direct α ‐allylic alkylation of unmodified aldehydes with allylic alcohols catalyzed by primary amine/Br⊘nsted acid has been developed. The N , N ‐dimethylethylenediamine/TfOH was identified as the optimal catalyst to promote this transformation via an enamine process in high yields (up to 88%) and with good diastereoselectivities (up to 9:1).
