A complete stereocontrol has been achieved by intermolecular addition of the bulky and nucleophilic silicon centered radical (TMS)3Si· to a chiral and conformationally flexible olefin. The stereoselectivity observed has been established by X-ray analysis and rationalized in terms of steric and Felkin-Anh stereoelectronic controls.
