Electrochemically generated base-promoted synthesis and biological activities of 2,4-disubstituted carbonotrithioates

摘要

The electrosynthesis of new 2,4-dialkylcarbonotrithioates, in satisfactory yields, starting from arylthiols and carbon disulfide using an electrogenerated base (EGB) that is reported to promote the reaction is reported. The EGB was prepared by pro-base-free electrolysis of acetonitrile under galvanostatic conditions using a sacrificial magnesium anode. The as-prepared compounds were fully characterized by H-1, C-13, F-19 NMR spectroscopy and mass spectrometry. The antimicrobial and cytotoxic activities of some representative compounds were investigated against human pathogenic bacteria, colon and lung cancer cell lines. Promising results were found against gram-positive and gram-negative bacteria and DLD-1 and A-549 cancer cell lines.
