Treatment of 1-iodo-1,5-diene 3 with Bu3SnH at 80°C afforded the 6- endo cyclized product 6. The reaction was extended further to achieve the transformation of 1-iodo-1,5,9,14-tetraene 10 into dodecahydrophenanthrene 11 under one electron reductive conditions via 6-endo,6-endo,6-exo cascade cyclization.
