Deprotonation of methyl phenylacetate with lithium diisopropylamide in tetrahydrofuran followed by trapping with trimethylsilyl chloride afforded an 81:19 mixture of E-and Z-silyl ketene acetals in agreement with a prediction by the calculation by Dauben. The E-silyl ketene acetal was readily isomet
It was found that in tetrahydrofuran solution, predominance (99.2%) of the highly stabilized Meyers enolate (1,5-dimethylpyrrolidin-2-one lithium enolate (1)) isomer with intramolecular Li-p C C coordination from the endo-face (Ct-endo) may be responsible for exceedingly high endo-selectivity in Mey
