Özet

Phenylselenyl and iodine induced chiral and achiral ring forming cyclisations creating bridged bicyclo-[3.2.1]- and cyclic ring N-hydroxylamines and bicyclo-[3.2.1]- ring amines occur stereo-, regio- and facially specifically that involve multiplication of chiral centres from one to two and three in one pot reactions in moderate to good yield. An example of bromine induced cyclisation and 1,3-dipolar cycloaddition creating isoxazolidine-ring were also reported.
