ABSTRACT
A [3 + 4] annulation of isatin N,N′-cyclic azomethine imine 1,3-dipole 1 with in situ-generated aza-oQMs has been established for the synthesis spirooxindole seven-membered scaffolds. These highly functionalized scaffolds were assembled moderate to good yields (up 96% yield). The novel displayed antitumor activities, which represented promising lead compounds drug discovery.
