Photochemical cycloaddition of 3-alkynylcycloalkenones 3a,b,c and 4 with tetramethylethylene (8) at ～40°C leads to mixtures of 1:1 adducts that arise largely from 1,5 closure of the biradical intermediate (eq 1), providing examples of a novel [3 + 2] cycl
Single step formation of novel tricyclic systems on [3 + 2] photocycloaddition of 3-(1-alkynyl) cyclohexenones to methoxyalkenes
Margaretha, Paul,Rathjen,Agosta, William C.
, p. 3245 - 3248 (1990)
Irradiation of 1b (λn350 nm) in tert-butyl alcohol solution containing 5 leads to the novel ring system 9b in a single step. Similar reactions occur between 1a and both 5 and 6. Mechanisms of these transformations are discussed.
Photoisomerization of 5,5-dimethyl-3-(3,3-dimethylbut-1-ynyl)-2-(pent-4-enyl)-cyclohex-2-enone to tert-butyl(4,4-dimethyl-2-oxotricyclo[7.3.0.0 1,6]dodec-6-en-7-yl)carbene

On irradiation (λ > 340 nm) cyclohexenone 1 is converted to a mixture of diastereoisomeric 4,4-dimethyl-7-(2,2-dimethylcyclopropyl)tricyclo[7.3.0.0 1,6]dodec-6-en-2-ones 2 via the title carbene 4, which can also be efficiently trapped both by m
