Abstract
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 methanol or by oxygen to afford methyl ethers 5a and 5b or the pivaloyl derivative 6, respectively.
