Abstract
Irradiation of a variety of model spirodiones related to the antitumou r antibiotic Fredericamycin A in various solvents at 300 nm furnishes quantitative yields of gamma-alkylidene gamma-butyrolactones; its rele vance to the typical shape alteration, photostability and consequent b iological response of Fredericamycin is discussed.
