Reactivity of secondary <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>N</mml:mi></mml:math>-alkyl acrylamides in Morita–Baylis–Hillman reactions
Résumés Anglais Français 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.

parthenolide in human breast cancer cells. We find that parthenolide, as well as other related exocyclic methylene lactone-containing sesquiterpenes, covalently modify cysteine 427 of focal adhesion kinase 1 (FAK1), leading to impairment of FAK1-dependent signaling pathways and breast cancer cell proliferation, survival, and motility. These studies reveal a functional target exploited by members of a
dissociation energy. Here we report a divergent radical transformation of a rich library of structurally diverse gem-dichloroalkanes by the controllable dechloroalkylation of alkenes by excited-state dinuclear gold catalysis. The gem-dichloroalkanes can be used to assemble C(sp3)–C(sp3) bonds as a chloroalkyl radical, an alkyl radical cation and a carbeneequivalent precursor for carbon-chain propagation
