The reaction was tolerant various arylboronic acids with diverse sensitive functional groups. Detailed studies showed that the carbonyl group in isatin oximes might be served as a carbonyl ligand or a controlled group playing important roles in the formation

  A copper-catalyzed selective cross-coupling reaction of 3-(hydroxyimino)indolin-2-ones with alkenyl boronic acids to access (E)-N-vinyl oxindole nitrones has been achieved under mild conditions. The studies showed that catalytic copper salt selectively gave mono N-vinylation products, while 2.0 equiv of copper salt provided double N-vinylation products. The control experiments revealed that the carbonyl

  Hydropyrrolo[2,3-b]indole is a privileged indoline motif, while its analogue, hydropyrrolo[3,2-b]indole, has been much less explored. Herein, we developed a cascade reaction of oxindole-derived nitrones with allenoates, providing straightforward access to the tetracyclic hydropyrrolo[3,2-b]indole scaffolds. Formation of multiple C–C/C–X bonds and cleavage could be achieved within one synthetic step
