- W3200133089 abstract "The Morita–Baylis–Hillman (MBH) reaction of secondary N-alkyl acrylamides, discarded up to now from investigations of the scope of activated alkenes, was studied. Optimization of the reaction conditions revealed that a balance must be found between activation of the MBH coupling reaction and that of the undesired competitive aldehyde Cannizzaro reaction. Using 3-Hydroxyquinuclidine (3-HQD) in a 1:1 water-2-MeTHF mixture provides the appropriate conditions that were applicable to a wide range of diversely substituted secondary N-alkyl acrylamides and aromatic aldehydes, giving rise to novel amide-containing MBH adducts under mild and clean conditions. Supplementary Materials: Supplementary material for this article is supplied as a separate file: crchim-117-suppl.pdf La réaction de Morita–Baylis–Hillman (MBH) de N-alkyl acrylamides secondaires, écartés jusqu’alors des travaux sur la variabilité des alcènes activés dans cette réaction, a été étudiée. L’optimisation de la réaction a fait apparaître un équilibre à trouver entre l’activation du couplage par réaction MBH et celle de la transformation de l’aldehyde par réaction de Cannizzaro. L’utilisation de la 3-hydroxyquinuclidine (3-HQD) et d’un mélange eau-2-MeTHF 1:1 comme solvant sont les conditions appropriées, applicables à une variété de N-alkyl acrylamides secondaires diversement substitués et d’aldéhydes aromatiques, menant à une série de nouveaux adduits MBH contenant un motif amide, dans des conditions douces et propres.
