04 - 120Preparation of Azetidines by 4-endo trig Cyclizations of N-CinnamylTosylamides. — Formation of azetidines via 4-endo cyclization of allylicamines is achieved. The reaction is proposed to proceed via a carbocationintermediate. — (ROBIN, SYLVIE; ROUSSEAU, GERARD; Eur. J. Org.Chem. (2000) 17, 3007-3011; Lab. Carbocycles, CNRS, Inst. Chim. Mol.Orsay, Univ.
