Chemical studies on 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one in connection with 6-methoxy-2-benzoxazolinone, an auxin-inhibiting substance of Zea mays L.
Some chemicalstudies on 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA, 1) and related compounds from ZeamaysL. 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
已经对来自玉米的2,4-二羟基-7-甲氧基-2 H -1,4-苯并恶嗪-3(4 H)-one(DIMBOA,1)和相关化合物进行了一些化学研究,其中DIMBOA (1)在室温下存在乙酸酐的情况下,已非常迅速地转化为6-甲氧基-2-苯并恶唑啉酮(MBOA,2),即一种玉米生长素抑制物质。因此,推测如体外的DIMBOA(1)的N-OH基团的酶促酰化作用对光致变色起重要作用。
