Synthesis and spectral analysis of novel 3-(4,6-diarylpyrimidin-2-yl)-2-phenylthiazolidin-4-ones
摘要:
Novel 3-(4,6-diarylpyrimidin-2-yl)-2-phenylthiazolidin-4-ones are synthesized by the multicomponent cyclocondensation reaction of the appropriate 2-amino-4,6-diarylpyrimidines, benzaldehyde, and thioglycolic acid catalyzed by dicyclohexylcarbodiimide. The synthesized compounds have been characterized by melting point, elemental analysis, MS, FT-IR, H-1 and (13) NMR spectroscopic data.

Catalytic Synthesis of Chalcones and Pyrazolines Using Nanorod Vanadatesulfuric Acid: An Efficient and Reusable Catalyst
Nanorod vanadatesulfuric acid (VSA NRs), as a recyclable and ecologically benign catalyst, was used for the one‐pot synthesis of chalcones and 1,3,5‐triaryl‐2‐pyrazolines (TAPs). Chalcones were prepared via the condensation of substituted acetophenones with aryl‐aldehydes under solvent‐free conditions. Subsequently, the synthesized chalcones were used for the catalytic synthesis of TAPs via two‐component
