متن کاملTriphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans
Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...

متن کاملSynthesis and in vitro Antibacterial Activity of Some Novel 2-Amino-4, 6-D Derivatives
Heterocyclic systems are one of the most important classes of organic compounds present in nature or synthesized in laboratory. These compounds posses an array of biological activities and are employed in the treatment of commonly occurring diseases. Keeping this in view, some new 2-amino-4,6-diarylpyrimidine from chalcones were synthesized. Eight novel 2-amino-4,6-diarylpyrimidine derivatives ...
متن کاملsynthesis 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)-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...
