ω-Halogenoalkyldichloroboranes are easily prepared in a stereocontrolled manner by hydroboration of ω-bromoalkylcycloalkenes or Diels-Alder reaction of (E)-alkenyldichloroboranes. Amination with benzylazide followed by an intramolecular nucleophilic substitution afforded the corresponding trans-pyrrolidines or piperidines
