Mechanism of formation of unusual photodegradation products from friedelin

Reiko Aoyagi; Takahiko Tsuyuki; M. Takai; T. Takahashi; F. Kohen; Robert Stevenson

Abstract From the photolysate of friedelin1, 3,4-seco-3-nor-friedelan-2-al2 and 3,4-seco-3-nor-friedelan-2-oic acid3 were obtained in addition to the expected photoproducts. Evidence is provided that2 and3 are autoxidation products of the ketene13 produced by α-cleavage of1 followed by hydrogen transfer.
