    • 3N at -40 °C was recorded in order to collect information about the enolization step. Under these conditions a single enolate is formed as demonstrated by the presence of a single vinyl signal at 4.60 ppm. The geometry of the enolate could not be determined by NOESY because the MeO signal was partially overlapped by the methylene signal of the triethylamine.
