Abstract: Intramolecular alkylation of α-4-chlorobutyrylcyclopentanone and α-4-chlorobu-tyrylcyclohexanone easily occurs at oxygen to form α-furanidin-2-ylenecyclopentanone and α-furanidin-2-ylenecyclohexanone, respectively, but the corresponding C-alkyla-tion does not take place. The C-alkylation of the related α-acetylcycloketones also hardly takes place and they are converted to the corresponding keto-esters with EtONa-EtOH.
