ANIONIC ACTIVATION OF STABILIZED YLIDES. A HIGHLY Z-STEREOSELECTIVE WITTIG REACTION OF (3-ETHOXYCARBONYL-2-OXOPROPYLIDENE)TRIPHENYLPHOSPHORANE WITH ALIPHATIC ALDEHYDES

Reaction of stabilized ylide 1 with carbonyl partners can be promoted via anionic activation of the ylide; the presence of charge is responsible for the high Z-selectivity in the direct formation of conjugated enones.
