Synthesis of nonenolizing 2-acylcyclohex-2-enones
Oliveira-Ferrer, Leticia,Schmidt, Kerstin,Margaretha, Paul
, p. 3818 - 3821 (2007/10/03)
Cyclohexanones 2b and 2c represent the first examples of nonenolizing 2-acylcyclohex-2-enones, as they bear H-atoms neither at C(4) or C(6) of the enone ring, nor at the C-atom vicinal to the exocyclic carbonyl group. While the CF3CO group in 2
