โฆ Synopsis
Any reaction that results in ring formation can be of considerable potential use in organic synthesis. It has been recognized for several years that a carbon-carbon double bond can experience insertion into a carbon-lithium bond resulting in the formation of a new carbor carbon u linkage.' If the double bond were incorporated in the lithium reagent (,J+), such an intramolecular reaction would result in ring formation.' In those systems which have been
