Completion of the Spectroscopical Data for the Synthesis of DIMBOA

Abstract

Cyclic hydroxamic acids like 2,4-dihydroxy-7-methoxy-2H-1 ,4-benzoxazin-3(4H)-one (DIM BOA) and 2,4-dihydroxy-2H-1 ,4-benzoxazin-3(4H)-one (DIBOA) are found in several plants playing an important role in the defense-system of plants against a variety of enemies. To investigate new mechanism and effects we synthesized the molecules using known synthetic pathways. Since the chemical data of DIMBOA are not complete or even false, we decided to publish the missing ones in this journal.
