Ru-catalyzed cyclocarbonylation of alpha- and beta-allenic sulfonamides: Synthesis of gamma- and delta-unsaturated lactams
[GRAPHICS] The Ru-catalyzed cyclocarbonylation of alpha- or beta -allenic sulfonamides in the presence of Ru-3(CO)(12) (1 mol %) and Et3N (1.5 equiv) under CO atmosphere (20 atm) in dioxane at 100 degreesC for 9 h gave heterocyclic gamma- and delta -unsaturated lactams in good yields.
