a series of 2-amino-4-aryl-3-cyano-7-(dimethylamino)-4 h -chromenes was synthesized by condensation of 3-(dimethylamino)phenol, an aromatic aldehyde and malonitrile in ethanol containing piperidine. the assignments of the structure of all synthesized compounds were based on spectral data (ir, mass and 1 h nmr). the cytotoxic activities of the synthesized compounds against six human tumor cell l...
متن کامل4-{(E)-[2-(4-Iodobutoxy)benzylidene]amino}-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The title Schiff base compound, C(22)H(24)IN(3)O(2), adopts an E configuration about the central C=N bond. The pyrazolone ring makes a dihedral angle of 49.68 (10)° with its attached phenyl ring. The phenolate plane makes dihedral angles of 16.78 (9) and 50.54 (9)°, respectively, with the pyrazolone ring and the terminal phenyl ring. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring...
متن کامل4-[(E)-(4-Diethylamino-2-hydroxybenzylidene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
In the title compound, C(22)H(26)N(4)O(2), the phenyl ring and hy-droxy-benzene group are twisted with respect to the central pyrazolone ring, making dihedral angles of 54.05 (5) and 21.80 (6)°, respectively. One of the ethyl groups is disordered over two positions with site occupancies of 0.872 (6) and 0.128 (6). The mol-ecular structure features short intra-molecular O-H⋯N and C-H⋯O contacts....
