, p. 645 - 648 (1994)
Migration of trimethylsilyl group from oxygen to α-carbon in silyl ketene acetals is effectively catalyzed by lanthanoid triflates under mild conditions.Scope and limitation of this rearrangement are presented.
Michael addition of methyl 2-(trimethysily)propenoate with organomagnesiums or organolithiums leading to 1:1 and / or 2:1 adducts and subsequent peterson olefination by condensation with carbonyl compounds

Michael addition of methyl 2-(trimethylsilyl)propenoate with organomagnesiums or organolithiums leads to 1:1 and/or 1:2 adduct anions which can be utilized in the subsequent step of Peterson olefination with carbonyl compounds. The 1:1/1:2 ratio depends u
Cleavage of Carbon-Carbon Bonds with High Stereochemical Control. 6. Asymmetric Synthesis of Chiral C-Centered Organosilanes by Haller-Bauer Cleavage of Optically Active, Nonenolizable α-Silyl Phenyl Ketones

Sequential alkylation and methylation of l-menthyl ester 10 provides diastereomeric mixtures in which 12 is slighthly enhanced over 13.Conversely, C-silation and alkylation of propionate ester 11 delivers 13 in excess.In either cause, a single chromatogra
