Oxidative free-radicalcyclization of Z-trisubstituted alkene 6a gave the expected octahydrophenanthrenes 9 (11%) and 10 (24%), lactone 17 (10%), and octahydrophenanthrene 4 (25%), which was obtained from E-trisubstituted alkene 1a. Cyclization of 6b provided the expected hydrindane 11 (25%), cyclopentane 18b (10%) formed by 5-exo cyclization, and hydrindane 5 (13%), which was obtained from E-trisubstituted
