Verwenden
t-Butyl Trimethylsilylacetate is used to prepare lithium enolates which can be alkylated;can
be alkenated with aldehydes and ketones;can be acylated;can
be reacted with Group 14 halides.
Most applications require initial formation
of the enolate (1) (eq 1), which is obtained as a white solid suspended
in THF, stable indefinitely at 78°C.
synthetische
an advantage of t-butyl trimethylsilylacetate
over its methyl and ethyl ester analogs is that it can be prepared
by C-silylation of the lithium enolate of t-butyl acetate at
78°C in THF (85–90% yield). Under the same conditions the
enolates of methyl and ethyl acetate give primarily O-silylated
products.The reagent has also been prepared by a rapid boron
trifluoride etherate catalyzed reaction of trimethylsilylketene
with t-butyl alcohol.
