Intramolecular Reactivity of Triplet Carbonylcarbenes |
|
| Authors: | Johannes Fien Wolfgang Kirmse |
| Abstract: | Through a double cyclization triplet carbonylcarbenes add smoothly to double bonds in the δ and ε position, but do not react intramolecularly with C–H bonds (see scheme). The addition reaction fails if the keto group is replaced with an ester group. |
