bromination of benzo-1, 4-thiazino[3,2-b]tropone (I) and its 8-isopropyl derivative (II) afforded 7- and/or 9-substituted compounds. In the case of nitration, 5-oxide and 5-oxide of 7-nitro derivative were obtained. The reaction of I or II with thionyl chloride unexpectedly gave the 7, 9-dichloro derivative of I, or four kinds of chloro derivatives of II.
获得了三种异构的苯并-1, 4-噻嗪酮。由二-或三卤托罗酮或3-溴托罗酮反应合成在七元环上被氯、溴、硝基或乙酰氨基取代的苯并1,4-噻嗪并[3,2-b]托酮与硝基或乙酰氨基,与邻氨基苯硫酚。苯并-1, 4-噻嗪并[3,2-b] 托酮 (I) 及其 8-异丙基衍生物 (II) 的溴化得到 7- 和/或 9- 取代的化合物。在硝化的情况下,得到7-硝基衍生物的5-氧化物和5-氧化物。I或II与亚硫酰氯反应出乎意料地得到I的7, 9-二氯衍生物或II的四种氯衍生物。
