  4-羟基-1,4-苯并噻嗪-和-苯并恶嗪-3（4 H）-酮（环状异羟肟酸）的乙酰化和乙酰氧基化

  摘要：

  用乙酰氯处理4-羟基-2 H -1，4-苯并噻嗪-3（4 H）-一（Ia）及其6-甲基衍生物（Ie），得到4-乙酰氧基衍生物（Ib和f）。然而，当乙酸酐为乙酰化剂时，获得了2-乙酰氧基-内酰胺（Ic和g）。相反，当将对应于（Ia）的砜与乙酰氯或乙酸一起加热时，仅分离出4-乙酰氧基-2 H -1,4-苯并噻嗪-3（4 H）-1，1-二氧化物（IIb）。酐。而4-乙酰氧基-内酰胺（IIIb）是通过乙酰氯在4-羟基-2 H -1,4-苯并恶嗪-3（4 H）-（IIIa），用乙酸酐处理该异羟肟酸，得到相应的6-和7-乙酰氧基-内酰胺（IIIc和e）的混合物。提出了形成这些乙酰氧基化合物的机理，并描述了它们的一些反应。

  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.

  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。
