Abstract

Substituted γ and δ-ketoaldehydes may be conveniently synthesized in two steps from imine carbanions, which are obtained by reaction with hyperbasic media. These anions are stable at low temperature (− 30°); they react with functional electrophiles to afford masked ketoaldehydes which may be cyclised into various cyclopentenones or cyclohexenones.
