PHOTOLYSIS OF 2,3-EPOXY-7,7-DIPHENYLBICYCLOHEPTAN-6-ONES AND 2-exo, 3-exo-DIHYDROXY-7,7-DIPHENYLBICYCLOHEPTAN-6-ONE

Photolysis of 2,3-endo-epoxy-7,7-diphenylbicycloheptan-6-one ( 2 ) in methanol gave products ( 4 ), ( 8 ) derived from an oxacarbene intermediate and the products ( 5 ) - ( 7 ), ( 9 ) derived from an initially formed alkenylketene.Photolysis of the

Photochemical Conversion of 7,7-Diphenyl-2,3-epoxybicycloheptan-6-ones into a 2-Oxabicyclohexan-3-one

Photolysis of the epoxide (3) or (5) gave the strained lactone (4) in 40 - 50percent yield; the bicyclic lactone (4) gave the functionalised cyclobutane (6) on treatment with acidic methanol, the structure of which was confirmed by X-ray analysis.
