A very simple method was developed for the direct, palladium‐free catalytic α‐allylic alkylation of aldehydes. The direct organocatalytic intermolecular α‐allylic alkylation reaction was mediated by a simple combination of Brønsted acid and enamine catalysis which furnished α‐allylic alkylated aldehydes and cyclohexanone in high yields and chemoselectivities. The reaction conditions are mild and environmental
A simple and direct α‐allylic alkylation of unmodified aldehydes with allylicalcohols catalyzed by primary amine/Br⊘nstedacid 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).
