Intramolecular Allylations of Carbonions

Abstract
In the general centaxt of examining a variety of organic, reactions which probably proceed via cyclic transition stares, we predicted scme years ago2 that the aniens (II) produced by the action of appropriate bases on allylic esters(I) would undergo intramolecular rearrangement to form the iscmeric carboxylate anions (III).
