The title compounds were synthesized by ruthenium-catalyzed ring-closingmetathesis of N-tosyl-N-(ω-alkenyl)aminomethylvinyl phosphonates, which were obtained from N-(ω-alkenyl)-N-tosylamides. These compounds, in turn, were prepared from unsaturated alcohols through the Mitsunobu reaction. This methodology gives access to five- and six-membered ring compounds. Additionally, chiral phosphonates can
