Furan-2(3H)- and -2(5H)-ones. Part 7. Photochemical behaviour of tetrahydro- and hexahydro-isobenzofuran-1-one systems: A mechanistic and exploratory study

The photoreactivity of two variations of the di-π-rnethane system involving the tetrahydro- and hexahydro-isobenzofuran structures 10 and 11 have been examined and compared with those of β-apolignans 1. The former, 9-phenyl-1,3,4,5,6,7,8,9-octahydronaphtho[2,3-c]furan-1-one 10a and 7-phenyl-1,3,4,7-tetrahydroisobenzofuran-1-one 10b, gave primarily the di-π-methane rearrangement products 18a and 18b, respectively, while the hexahydro substrate, 7-phenyl-1,3,4,5,6,7-hexahydroisobenzofuran-1-one 11, afforded mainly the photoreduced products 21-24. This difference in chemoselectivity is explained in terms of the variant configuration of the phenyl group, an axially orientated one migrating most effectively. A new pathway for the reaction leading to the cyclopropano product 18a or 18b, by way of another cyclopropano derivative 19a or 19b, respectively, is described.
