We have recently succeeded in preparing a series of spiro[2.5]octa-k,i'-dien-6-ones (1) and find the photochemistry oftheae ccmpowds to differ from that reported (2a-c) for the parent dienone 2 (B-c). Schuster and coworkers report that irradiation (>28&) of an ethereal solution of 2 lmds to intermed
Photolysis of benzo[a]spiro [2,5]octa-1,4-dien-3-one derivative 8a afforded spiro-fused tetracycles 10 as a pair of diastereomers in 1.7:1 ratio. The photochemical process occurred by cycloaddition of the intermediate-sulfone stabilized biradical 9 to the tethered olefin. Photolysis of dienone 8b ga
