Abstract

Quinone bisketals are protected quinone derivatives' which are readily converted to synthetically versatile quinone monoketals2 by acid hydrolysis. However, for preparation of highly reactive and/or acid-labile quinone derivatives (eg, quinone imines3), a carbonyl protecting group which could be deblocked under mild, neutral conditions in nonnucleophilic media is desirable (Scheme I). One candidate for such a carbonyl ...
