Department of Organic Chemistry, Indian Association for the Cultivation of Science, Jadavpur, Calcutta-700 032 Manuscript received 12 August 1998 Attempted photolytic ethylene addition to lactone 3 affords only the intramolecular cycloadduct 5 and the rearranged product.6, the latter arising from a photo-ene reaction. Similarly lactone 4 also furnishes the cycloadduct 8 and the ene product 9. Basic hydrolysis of 6 followed by esterification produces the hydroxydiester 10 which on oxidation furnishes the highly functionalised bicyclo(3.2.1)octane derivative 11. |
