ChemInform Abstract
The title reaction is of synthetic utility in carbocyclic ring construction. It is demonstrated that in general these reactions appear to be relatively little effected by the presence of substituents. However, if the olefin is not easily accessible as in the case of (XVI) only the corresponding intermolecular product (XVIII) is obtained. Also, neither di- nor trisubstituted alkenes give cyclized products, only intermolecular hydroxycyclopropanation takes place.
