The cephalosporin triflate (1) reacts with a wide variety of olefins and acetylenes in the presence of a base to give 2,3-fused cyclobutane and cyclobutene derivatives, respectively.
Cycloadditions of cephalosporins. A comprehensive study of the reaction of cephalosporin triflates with olefins, acetylenes, and dienes to form [2 + 2] and [4 + 2] adducts

Novel polycyclic cephalosporins are formed by the reaction of cephalosporin triflates with various unsaturated compounds in the presence of Hunigs base. 2,3-Fused cyclobutane and cyclobutene cephems are obtained with olefins and acetylenes, respectively,
