title: Desymmetrizing asymmetric ring expansion: stereoselective synthesis of 7-membered cyclic beta-keto carbonyl compounds with an alpha-hydrogen.
abstract: Ring expansion of symmetrically substituted cyclohexanones with N-alpha-diazoacetyl camphorsultam was devised as a stereoselective pathway to the functionalized 7-membered cyclic beta-keto carbonyls having a kinetically stabilized alpha-hydrogen.
