摘要：

Treatment of appropriately substituted 5,9-diene, 5,9,13-triene and 5,9,13,17-tetraene phenoselenyl esters, e.g. 1a, 9 and 14, with Bu(3)SnH-AIBN is shown to lead to linear and angular six-ring fused polycycles, viz 2, 11 and 15 respectively, via consecutive 6-endo-trig modes of cyclisations starting from the corresponding polyolefin acyl radical intermediates.
