Synthesis of multicomponent crystals composed of 4-amino-1-methylpyridinium <i>p</i>-toluenesulfonate and phenol derivatives

Synthesis of Phosphorus Derivatives via Multicomponent Reactions

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields. 

Triphenylphosphine 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 ...

synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides

Studies on the Synthesis, Growth, Characterization of 2-amino- 5-nitropyridinium-toluenesulfonate Single Crystals

Synthesis 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 ...
