Synthesis and cytotoxic activity of some 2-amino-4-aryl-3-cyano-7-(dimethylamino)-4H-chromenes
A series of 2-amino-4-aryl-3-cyano-7- (dimethylamino)-4H-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 ...

متن کاملZirconocene complexes bearing novel 3-dimethylamino-1,2-dihydropentalene derived ligand systems.
Coupling of the N,N-dimethylacrylamides 6a-c with cyclopentadienide resulted in the formation of the substituted 3-dimethylamino-1,2-dihydropentalnenes 2a-c. Deprotonation followed by metallation with CpZrCl(3)·DME gave the substituted zirconocenes 12a-c. The reaction of 3-dimethylamino-1-methyl-dihydropentalene 2a with ZrCl(2)(NMe(2))(2)·2THF resulted in a unique coupling between a pair of the...
متن کامل3-(3-Nitrobenzyl)-4H-chromen-4-one
In the title compound, C16H11NO4, the dihedral angle between the 10-membered coplanar chromone ring system and the benzene ring is 77.83 (3)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
