Enantioselective Cyanation/Brook Rearrangement/C-Acylation Reactions of
Catalyzed by Chiral Metal Alkoxides. — Treatment of aromatic acylsi06- 092 Acylsilanes
lanes with cyanoformates in the presence of chiral Al-catalyst offers a new enantioselective approach to malonic acid derivatives of type (IV) and (VII). The nature of metal
and ligand as well as the concentration strongly affect the outcome of the reaction
sequence. The products can smoothly be transformed into α-hydroxy-α-aryl-β-amino
acids derivatives and β-lactams. — (NICEWICZ, D. A.; YATES, C. M.; JOHNSON*,
J. S.; J. Org. Chem. 69 (2004) 20, 6548-6555; Dep. Chem., Univ. N. C., Chapel Hill,
NC 27599, USA; Eng.) — Jannicke
