Abstract

Aldehydes undergo an efficient E-stereoselective Horner-Wadsworth-Emmons olefination by generation of phosphonate carbanion with lithium hydroxide. The reaction proceeds satisfactorily with linear, cyclic, polyfunctional ketones in the presence of activated zeolites and by the slow addn. of the base.
