A new approach to a diastereoselective cationic cyclization by stereocontrol due to the bicyclo[2.2.1]heptene moiety in a chiral γ-hydroxy lactam is described. The diastereoselective reaction followed by Diels–Alder cycloreversion has been successfully applied to a chiral synthesis of (+)-indolizidine and (+)-laburnine (=trachelanthamidine).
