Abstract

Abstract Some chemical studies on 2, 4-dihydroxy-7-methoxy-2H-1, 4-benzoxazin-3 (4H)- one (DIMBOA, 1) and related compounds from Zea mays L. have been carried out, where DIMBOA (1) has been very rapidly converted into 6-methoxy-2-benzoxazolinone (MBOA, 2), an auxin-inhibiting substanse of maize, in the presence of acetic anhydride at room temperature. Therefore, such an enzymatic acylation of N-OH group of DIMBOA (1) as in ...
