strategy. DFT analysis, initially used to identify synthesis candidates, was also employed to rationalize the propensity for cycloaromatization of the compounds. In all cases studied the halogen atom had a strongly retardative effect on the thermal Bergmancycloaromatizationreaction. The isolation of the first C-9 monochloroenediyne is noteworthy, and may find application in prodrug design.
