Dowex-50W-Promoted Synthesis of Oxazoline, Imidazoline and Thiazoline Derivatives
نویسندگان
چکیده
Dowex-50W-hyodrgen ion exchange resin was used as a reusable catalyst for the synthesis of oxazoline, imidazoline and thiazoline derivatives through condensation reaction between arylnitriles and 2-aminoalcohol, ethylenediamine or 2-aminoethanthiol. This process provides several advantages such as excellent yields of the products, simple operation, convenient separation and inexpensive and recyclable catalyst.

The geometries of various tautomers and isomers of 2-methylamino-2-imidazoline, 2-methylamino-2oxazoline, 2-methylamino-2-thiazoline, 2-phenylamino-2-imidazoline, 2-phenylamino-2-oxazoline, and 2-phenylamino-2-thiazoline have been studied using the Becke3LYP/6–31+G(d,p) DFT, ONIOM(Becke3LYP/6–31+G(d,p):HF/3–21G∗) and ONIOM(Becke3LYP/6–31+G(d,p):AM1) methods. The optimized geometries indicate th...
متن کاملSynthesis of the biologically active natural product cyclodepsipeptides apratoxin A and its analogues.
This paper describes the synthetic studies conducted on a marine natural product, cyclodepsipeptide apratoxin A. Total synthesis of the oxazoline analogue of apratoxin A was achieved. The conversion of oxazoline to thioamide, as well as thioamide formation from a serine-derived compound, were both unsuccessful. However, thiazoline formation from a cysteine-derived compound led to the total synt...
متن کاملSynthesis of new 1,3-thiazoline-2-thiones as potential antimycobacterial agents
As a continuation of our efforts in developing new antimycobacterial agents, a series of new 1,3-thiazolidine-2-thione derivatives were synthesized. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. The analysis of theoretical toxicity risks,drug-likeness and drug-score for these series using Osiris program showed acceptable results.
