Abstract
Alkyl (n+1)-oxobicyclo[n.1.0]alkane-1-carboxylates have been prepared from phosphoniosilylation and cyclopropanation of α,β-unsaturated ketones, and alkyl 4-oxocycloalkanecarboxylates have been prepared in good yield via endocyclic ring expansion reactions of activated cyclopropyl ketone derivatives containing ester group mediated by 3 equiv of SmI2-induced single electron transfer in THF/MeOH.
