Abstract
Attempted reactions of 16 wiht several acetic acid dianon equivalents were unsuccessful, possibly due to competing reactions from the quinone. Accordingly, 16 was converted to 1719 as shown. AnalogyZo suggested that a metal phenoxide species (generated in situ) might be less vulnerable to nucleophilic attack by external enolates.
