3-[(E)-Benzylidene]indolin-2-one [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the title indolin-2-one derivative, C(15)H(11)NO, the phenyl ring and the oxoindoline fused-ring system (r.m.s. deviation = 0.011 Å) are aligned at 48.52 (6)°. In the crystal, inversion-related mol-ecules form an N-H⋯O hydrogen-bonded dimer via an eight-membered {⋯HNCO}(2) synthon.

Total Synthesis of the Spirocyclic Bis‐Indole Alkaloid (−)‐Owerreine via a [4+2] Annulation

Angewandte Chemie, EarlyView.
The total synthesis of the bis‐indole alkaloid (−)‐owerreine has been accomplished by a diastereoselective [4+2] annulation between an enamine and an α,β−unsaturated indolenine precursor to form the 3‐spirocyclic tetrahydropyridine linkage of the natural product. DFT calculations allow an understanding of the mechanism of the key annulation.

Synthesis, characterization and evaluation of antidiabetic activity of novel indoline derivatives

Bangladesh Journal of Pharmacology, 2017
Series of indoline derivatives were synthesized using N-(4-aminophenyl)indoline-1-carbothiamide as a precursor. The confirmation of synthesized compounds was done by 1H-NMR, 13C-NMR, LC-MS (ESI) and FT-IR.
