    Rearrangement of 4-acetoxy-2H-1,4-benzoxazin-3(4H)-one.
    摘要:
    4-乙酰氧基-2H-1, 4-苯并恶嗪-3 (4H)-酮(3)根据反应条件进行重排或亲核攻击,得到苯并恶嗪酮的2-、5-、6-和7-取代衍生物。 5-和7-取代产物的形成被解释为对由3的N-O键杂解形成的阳离子(14)的亲核攻击。对于苯并恶嗪酮的6-取代衍生物的形成,氧的参与苯并恶嗪酮 1 位原子(即形成氧鎓离子 18)很重要。形成 2-取代产物的一个可能机制还涉及氧鎓离子 (19)。乙酰氧基苯并嗪酮化学的这些新颖方面可能有助于理解谷类植物中抑制素的作用机制。

  • Optimization of Benzoxazinones as Natural Herbicide Models by Lipophilicity Enhancement

    Benzoxazinones are plant allelochemicals well-known for their phytotoxic activity and for taking part in the defense strategies of Gramineae, Ranunculaceae, and Scrophulariceae plants. These properties, in addition to the recently optimized methodologies for their large-scale isolation and synthesis, have made some derivatives of natural products, 2,4-dihydroxy-(2H)-1,4-benzoxazin-3-(4H)-one (DIBOA) and its 7-methoxy analogue ( DIMBOA), successful templates in the search for natural herbicide models. These new chemicals should be part of integrated methodologies for weed control. In ongoing research about the structure-activity relationships of benzoxazinones and the structural requirements for their phytotoxicity enhancement and after characterization of the optimal structural features, a new generation of chemicals with enhanced lipophilicity was developed. They were tested on selected standard target species and weeds in the search for the optimal aqueous solubility-lipophilicity rate for phytotoxicity. This physical parameter is known to be crucial in modern drug and agrochemical design strategies. The new compounds obtained in this way had interesting phytotoxicity profiles, empowering the phytotoxic effect of the starting benzoxazinone template in some cases. Quantitative structure-activity relationships were obtained by bioactivity-molecular parameters correlations. Because optimal lipophilicity values for phytotoxicity vary with the tested plant, these new derivatives constitute a more selective way to take advantage of benzoxazinone phytotoxic capabilities.

    4-Acetoxy-2H-1, 4-benzoxazin-3 (4H)-one (3) undergoes rearrangement or nucleophilic attack to give 2-, 5-, 6-, and 7-substituted derivatives of the benzoxazinone according to the reaction conditions. The formation of 5- and 7-substituted products was interpreted in terms of nucleophilic attack on the cation (14) formed by the heterolysis of the N-O bond of 3. For the formation of 6-substituted derivatives of the benzoxazinone, participation of the oxygen atom at position 1 of the benzoxazinone (that is, formation of an oxonium ion, 18) is important. A possible mechanism for the formation of 2-substituted products also involves an oxonium ion (19). These novel aspects of acetoxybenzoxazinone chemistry may contribute to an understanding of the mechanism of the actions of the prohibitins in cereal plants.
