摘要：
On irradiation (lambda > 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.
