A series of quinoxaline 1,4-di-N-oxide analogues were prepared from benzofurazan N-oxide derivatives and β-diketone ester compounds by the improved Beirut reaction. The structures of the target products were characterized by NMR, MS, IR and elemental analysis measurements, and that of
Use of isopropyl alcohol as a solvent in Ti (O-i-Pr) 4-catalyzed Knoevenagel reactions.
Archives of toxicology, 71(9), 550-555 (1997-01-01)
The fungicide isoprothiolane (diisopropyl 1,3-dithiolane-2-ylidenemalonate) decomposes to the diisopropyl esters of malonic acid (DM), chloromalonic acid (DCM) and dichloromalonic acid (DDCM) upon aqueous chlorination. In this study, the cytotoxicity of these compounds was examined using rat hepatocytes cultured on Matrigel.
