                                    The tributyltin hydride + azobisisobutyronitrile (AIBN) mediated free radical carbocyclization of precursors 1-9, 48 and 49 is described. The resulting carbocycles have been obtained in moderate yield and good diastereoselectivity. These polyfunctionalized, enantiomerically pure cyclopentane derivatives are useful intermediates for further manipulation.
