摘要: 2,4-Dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA) and its desmethoxy derivative (DIBOA) are major allelochemicals produced by corn, wheat, rye related monocotyledons. These benzoxazinone derivatives have a wide variety of biological actions, including antifungal mutagenic activities. Structure-activity relationships these compounds their (benzoxazinoids), the reactivity benzoxazinoids with nucleophiles, substituent effects 7-methoxy 2-hydroxy groups discussed in relation to molecular mechanisms
