Irradiation of 1-phenylphosphole oxide-cyclopentadiene adduct gave a caged product, whereas similar irradiation of 1,2,5-triphenylphosphole oxidecyclopentadiene adduct afforded a cleavaged product. Previous studies 2) from this laboratory showed that the Diels-Alder dimer of 1-phenylphosphole oxide
## Abstract The __Diels__–__Alder__ reaction was applied to 4,5‐epoxymorphinan opioids to generate a novel aromatic cycloadduct at C(7)C(8): Thermolytic cleavage of sultine **8** produced the reactive diene __o__‐quinodimethane **7** which condensed favorably with codeine (**11**), but not with co
