Tricyclic Flavonoids Derived from JV^iV-Dimethyldithiocarbamates as Potential Antimicrobial Agents

摘要

Three new Bavanones bearing a carbodithioate moiety have been obtained by reacting the corresponding N,N-dimethyIdithiocarbamates with various aminals. These were then converted to 1,3-ditiiiolium tricyclic flavonoids using a sulfuric acid / acetic acid mixture. All new flavonoids with promising antimicrobial properties were analyzed using NMR andIR spectroscopy and the proposed structures were confirmed.
