Abstract:

Pyrazoles constitute one of the most important classes of heterocyclic compounds due to their interesting chemical and biochemical features. Researchers have studied many pyrazole containing structures for almost over a century in order to investigate the various biological activities possessed by these molecules. A new and important trend in these studies is to produce ferrocenyl substituted pyrazoles since ferrocene attracts considerable interest in the research field of organometallic and bioorganometallic chemistry because of its valuable chemical characteristics like high stability, low t

Abstract:

Project I. Cinchona alkaloid-derived quaternary ammonium salts have been successfully used as phase-transfer catalysts, particularly in asymmetric alkylations. Our group applied this type of catalyst in the synthesis of β-hydroxy α-amino acids via aldol reactions and discovered that the Park-Jew catalyst afforded good yields and good enantiomeric excess of the syn diasteromers, but negligible diastereoselectivity. This project was therefore focused on the synthesis of novel cinchonidine-derived catalysts with the Park-Jew catalyst as the lead structure. The C3 position of cinchonidine nucleus

Les lymphomes à grandes cellules anaplasiques ou ALCL (Anaplastic Large-Cell Lymphoma) sont des cancers appartenant à la famille des lymphomes de type non-Hodgkin. La majorité des ALCL est issue d'une translocation t(2;5)(p23;q35) donnant lieu à la formation d'une protéine de fusion appelée NPM-ALK. A ce jour, peu d'inhibiteurs présentent de bonnes activités contre cette protéine chimérique.

Furan and benzene alternating oligomers are prepared by using our usual furan annulation approach. When the divinyloligoaryl or dialkynyloligoaryl is used, dialdehyde can be conveniently constructed by Heck or Sonogashira cross-coupling reaction. Dialdehydes can be used for further extension of these conjugated systems. Attempts to annulate these dialdehydes with functionalized dithioacetals are found to be su

The transition-metal-catalyzed coupling reaction of terminal alkynes with aryl halides and vinyl halides are attractive methods for preparing alkynes and enynes. More recently, the exclusive use of copper, as catalyst has gained significant attention in the Sonogashira-type reaction owing to the low cost of copper salts. Typically, the combination of palladium and copper as catalyst is quite popular. However, palladium is highly toxic and expensive

The previously described 2-aryl-4-chloro-3-iodoquinolines were prepared following literature procedure and in turn converted to the corresponding hitherto unknown 2-aryl-3-iodo-4-(phenylamino)quinoline derivatives using aniline in refluxing ethanol. These 2-aryl-3-iodo-4-(phenylamino)quinolines were reacted with allybromide in ethanol at room temperature to afford 4-(N,N-allylphenylamino)-2-aryl-3-iodoquinoline derivatives. The 2-aryl-3-iodo-4-(phenylamino)quinoline and 4-(N,N-allylphenylamino)-2-aryl-3-iodoquinoline derivatives were subjected to metal-catalysed carbon-carbon bond formations.
