found that the cytotoxic furanones induced lipid peroxidation, determined by TBARS assay. Thus, cytotoxicity of the active compounds could be associated with ROS production. Additionally, it must be taken into account that all cytotoxic compounds contain an electrophilic carbon atom in position 4, which can explain, through a non-specific reactivity with nucleophiles, the cytotoxic activity of these
Vitamin B12: An efficient type catalyst for the one-pot synthesis of 3,4,5-trisubstituted furan-2(5 H )-ones and N -aryl-3-aminodihydropyrrol-2-one-4-carboxylates
Abstract VitaminB12 was applied as catalyst for the one-pot three-component synthesis of 3,4,5-trisubstituted furan-2(5H)-ones from the condensation between aldehydes, amines and dialkylacetylendicarboxylates at ambient temperature in EtOH. In addition, N-aryl-3-aminodihydropyrrol-2-one-4-carboxylates were synthesised using mentioned catalyst at ambient temperature in EtOH from condensation between
with average sizes ranging from 53 to 60 nm measured by DLS technique. Next, the catalytic activity of pure and Al-doped ZnO nanopowders was investigated in terms of synthesis of 3,4,5-substituted furan-2(5H)-one derivatives using the three-component reaction of aldehydes, aromatic amines, and acetylenic esters. This procedure has advantages such as high yields, simple methodology, and easy work-up
Use of green and biodegradablecatalyst in organic synthesis is undeniable. Easy access, inexpensive, natural and green catalysts are valuable. In this study, a green procedure by using pectin as a green and naturalcatalyst for the one-pot synthesis of dihydro-2-oxopyrroles and 3,4,5-trisubstituted furan-2(5H)-ones at ambient temperature in aqueous media has been developed. This methodology has some
1-Butyl-3-methylimidazolium hydrogen sulfate [bmim]HSO4: an acidic ionic liquid was used as a catalyst for the synthesis of heterocyclic compounds 3,4,5-substituted furan-2(5H)-ones from aniline derivatives, dialkyl acetylenedicarboxylates and aromatic aldehydes at 75 °C. Solvent-free conditions, shorter reaction time, and good yields (71-94%) are some of advantages.
1-Butyl-3-methylimidazolium hydrogen sulfate [bmim]HSO4: 一种酸性离子液体被用作催化剂,用于在 75 °C 下从苯胺衍生物、乙炔二羧酸二烷基酯和芳香醛合成杂环化合物 3、4、5-取代的呋喃-2(5H)-酮。该方法具有无溶剂条件、反应时间短、收率高(71-94%)等优点。
