ChemInform Abstract
The iminium triflate salt/imine protocol for the title synthesis of cis-2-azetidinium salts (isolated as perchlorates), such as (IV) and ( VIII), is complementary to the one employd for the trans-specific chloride analogues and may constitute an alternative route to that of the Staudinger reaction for β-lactams, such as (V).
