This investigation began in an attempt to develop an efficient new synthetic method for the stereospecific synthesis of the Y-alkylidena double bond in the sesquiterpene, freelingyne, I (1). Although methods are avsilable for the preparation of enol la&ones they usually lack stereochemical control.

Sequential dichlorocyclopropanation and ethoxide induced lactone cleavage of bridgehead enol lactones affords a stereocontrolled synthesis of 2-chlorocycloheptenones. Bridgehead enol lactones (2),' prepared by Type 2 intramolecular Diels-Alder cycloaddition of trienol esters (1) have been shown to b
