In the case of an α,β-or β,γ-unsaturated aldehyde as the nucleophilic reagent under the same conditions: trans-2-methyl-2-butenal, 0% yield; 2-methyl-3-butenal, 67% yield. These facts indicate that a β,γ-unsaturated aldehyde has to be used for the direct vinylogous Mannich-type reaction. 2-Methyl-3-butenal was prepared by the following literature using crotyl bromide instead of allyl bromide: Crimmins, M. T.; Kirincich, S. J.; Wells, A. J.; Choy, A. L. Synth. Commun. 1998, 28, 3675. Spectroscopic data: see the Supporting Information.
