Enone Cycloadditions and Rearrangements

IntraBolecular.- The apnide (1) is converted on irradiation in benzene/ethanol into a complex mixture of products (2)-(5). [Pg.173]

A previous report gave an account of the intramolecular photocyclization of the enone (12) to afford the head-to-head adduct (13). The adduct (13) obtained in this way has been used as a starting material for pentalenolaotone G methyl ester (14). While the above reaction only yields a [Pg.173]

A 70X yield of the adduct (24) is obtained on brief irradiation through Pyrex of a hexane solution of the enone [Pg.179]

The intramolecular photoaddition of the enone (32) in chlorobenzene using wavelengths 350 nm affords the adducts [Pg.179]

An efficient route to the synthesis of the cycloalkanones (37) involving the intramolecular photochemical cyclization of the enones (38) has been described. This yields the tricyclic [Pg.179]
