Novel derivatives of chromenone bearing an N -carbamothioyl moiety were synthesized and evaluated for their soybean 15-LOX inhibitory activity. Synthesis of the target compounds was started from 7-hydroxy-2H-chromen-2-one. It was reacted with 1-fluoro-2(4)-nitrobenzene to obtain the corresponding nitrophenoxy-chromenone derivative. Reduction of the nitro group was achieved in the presence of Zn/NH4Cl and reaction of the latter compound with in situ prepared benzoyl isothiocyanate led to the formation of the title compounds. |
