Azetidinium salts, ring expansion

Like their monocyclic analogs (see Section 5.09.2.2.7) bicyclic azetidinium salts are subject to nucleophilic ring opening. Quaternary salt (27) can react with a nucleophile either at C-5 or C-7 producing the ring expansion (28) or direct substitution products (29), respectively (64HCA745, 69AG(E)962. ... [Pg.344]
