Electrophile induced bridged-ring forming cyclisations creating azabicyclo-[3.3.1]- and azabicyclo-[3.2.1]-nitrones, followed by cycloaddition, occur stereo-, regio- and facially specifically in good to excellent yield. Chiral bridged-ring systems have been synthesised that involve multiplication of chiral centres from one to six and one to seven in one pot reactions. (C) 2002 Elsevier Science Ltd.
