The photoreactivities of 2-benzoylcycloalkanones were shown to be controlled by their ring conformation; 2-benzoylcycloalkanones underwent the TypeII elimination and/or cyclization, and/or the α-cleavage reaction.
A carbon–carbon bond was formed at the β-position of cyclicketones in a one-pot manner by oxidation with N-tert-butylbenzenesulfinimidoyl chloride, followed by the reaction of malonic acid esters or potassium cyanide.
