Ethyl Lithio trimethylsilyl acetate

Schank, K. Beck, H. Werner, R, Helv. Chim. Acta 2000, 83, 1611. [Pg.293]

Alkylations. Alkylation of the title enolate (1) with alkyl iodides in the presence of HMPA allows for the preparation of higher a-silyl esters.  [Pg.293]

Ester enolate (1) can be alkylated by vinyl halides in the presence of a nickel catalyst to afford a-trimethylsilyl-/ ,)z-unsaturated esters. These products react with a wide variety of electrophiles in the presence of a Lewis acid to provide y-subsituted [Pg.293]

Solubility sol ethereal solvents reacts with protic solvents. [Pg.293]

Preparative Methods available by reaction of ethyl trimethylsi-lylacetate with lithium diisopropylamide, lithium isopropylcy-clohexylamide, or lithium dicyclohexylamide in THF at low temperature.  [Pg.293]

Peterson olefination.1 This reaction usually shows little or no selectivity. In contrast, the reaction of ethyl lithio(trimethylsilyl)acetate with a-substituted cyclohexanones can show moderate to high (Z)-selectivity. (Z)-Selectivity is somewhat higher in reaction with ethyl potassio(trimethylsilyl)acetate or r-butyl lithio(trimethylsilyl)acetate, but yields... [Pg.228]
