Synthesis of acylsilanes via nickel-catalyzed reactions of α-hydroxyallylsilanes.
Résumé
The redox isomerization processes and tandem isomerization-aldolization reactions, mediated by nickel catalysts, offer new versatile entries to acylsilanes. For the second reaction, high diastereoselectivities, up to 98:2, have been obtained with bulky substituents on silicon.
