Abstract
Asymmetric synthesis of 1-oxaspiro[4.6]undecan-7-one and spiro[4.6]und ecanes has been achieved by a regio- and stereoselective tandem oxidat ive ring expansion-cyclization reaction of chiral bicyclo[4.1.0]heptyl sulfides bearing an alcohol or electron-rich olefin in the C-6 side c hain via a cation radical intermediate.
