The condensation of phenylaziridines (3a/3b) with 3-cyclopentenylsilane (4) in presence of BF3.Et20 yielded amino-cyclopentenyl adducts (Sa-8a) and (Sb-8b). Heterocyclisation of the 03-amino-olefins assisted by Pd(OAc)2 afforded the azabicyclo adducts 2a/2'a and 2b/2'b. Oxidation of the internal dou
