Tributylphosphane-promoted [3 + 2] annulation of 3-hydroxyoxindoles with acrylates: Synthesis of spirocyclic oxindole-lactones
The tributylphosphane-promoted [3 + 2] annulation reactions of 3-hydroxyoxindoles with acrylates have been developed to give a variety of pharmaceutically attractive spirocyclic oxindole-lactone derivatives in good to excellent yields. The structures of all the compounds were confirmed by 1H NMR, 13...
