摘要：

A radical-based 5-exo-dig cyclisation, initiated by addition of a trichloromethyl radical to an acyclic acetylenic ketone with an appropriately positioned double bond, has been employed to produce a variety of cyclic haloalkylidene cyclopentanones in moderate to excellent yields and with a high degree of stereoselectivity for the (E)-isomer.
