In the title compound, C(17)H(15)N(3)O(2)·C(2)H(6)O, Schiff base molecules are linked by a hydr-oxy-amido hydrogen bond into a helical chain running along the b axis. This chain is consolidated by two other hydrogen bonds; the ethanol solvent mol-ecule is a hydrogen-bond donor to the amide group and a hydrogen-bond acceptor for the indolyl NH group of an adjacent Schiff base mol-ecule.

The Ni atom in the centrosymmetric title compound, [Ni(C(10)H(9)N(4)S)(2)], is N,S-chelated by the deprotonated Schiff bases in a square-planar geometry. The -CH=N-N=C(S)-NH(2) frament is planar. Adjacent mol-ecules are linked by hydrogen bonds between the indolyl -NH (donor) site and the double-bond =N- (acceptor) site of an adjacent mol-ecule, forming a layer motif.

The indolyl portion of the title mol-ecule, C(11)H(8)FNO(3), is flat, the five- and six-membered rings making a dihedral angle of 0.815 (6)°. Inter-molecular N-H⋯O hydrogen bonds link adjacent mol-ecules into a linear chain. Slipped π-π stacking inter-actions between two neighboring indole groups further consolidate the mol-ecules into a three-dimensional supra-molecular architecture [centroid-...

The Ni atom in the crystal structure of the centrosymmetric title compound, [Ni(C(19)H(15)N(6)S)(2)]·2C(2)H(6)OS, is N,S-chelated by the deprotonated Schiff bases in a square-planar geometry. The -CH=N-N=C(S)-NH-N=CH- frament is planar. The two indolyl -NH (donor) sites inter-act with dimethyl sulfoxide mol-ecules to furnish a layer motif.

Asymmetric addition of indoles to cyclic α-diaryl-substituted N-acyl imines, which are generated in situ from 3-aryl 3-hydroxyisoindolinones, is described. The transformation proceeds smoothly with a broad range of indoles and isoindolinone alcohols using a SPINOL-derived chiral Brønsted acid catalyst to afford α-tetrasubstituted (3-indolyl)(diaryl)methanamines in excellent yields and enantiose...

A mild and efficient method catalyzed by α-chymotrypsin was developed for the synthesis of bis(indolyl)methanes through a cascade process between indole and aromatic aldehydes. In the ethanol aqueous solution, a green medium, a wide range of aromatic aldehydes could react with indole to afford the desired products with moderate to good yields (from 68% to 95%) using a little α-chymotrypsin as c...

A new optimal synthetic scheme for antibacterial compounds combining tris-(1-alkyindol-3-yl)methylium and 3-(indol-1-yl)maleimide in their structures was developed. The proposed method provided a significant increase the product yield, reduced labor intensiveness number of steps, used readily accessible starting reagents. Agood yield achieved 3-(formylindol-1-yl)-4-chloromaleimide, universal pr...

Ascorbigen (ABG) belongs to the glucosinolate family and occurs mainly in Brassica vegetables. It is formed by its precursor glucobrassicin. Glucobrassicin is enzymatically hydrolyzed to indole-3-carbinol, which in turn reacts with L-ascorbic acid to ABG. The degradation of glucobrassicin is induced by plant tissue disruption. The ABG formation depends on pH and temperature. The degradation of ...
