Popis:	2H-1,4-Benzoxazin-3(4H)-one has been identified as an intermediate in the biosynthesis of cyclic hydoxamic acids in maize by showing that the deuterium labelled compound is incorporated into DIMBOA with high retention of deuterium and high efficiency, by trapping radioactivity from [ 14 C] anthranilic acid in a pool of unlabelled benzoxazinone administered to maize shoots, and by showing that benzoxazinone is oxidized to DIBOA by maize microsomes in an NADPH- and oxygen-dependent reaction.
