  Heating of o-acetoxybenzoyl azides 6–10 in toluene leads to the Curtius reaction, which, when followed by closure of oxazolone ring with concomitant migration of acetyl group from oxygen to nitrogen, produces 3-acetoxybenz[d]oxazol-2(3H)-ones 11–15, which undergo hydrolysis with hot dilute hydrochloric acid to furnish benz[d]oxazol-2(3H)-ones 17–21. Thermal reaction of 2-hydroxy-5-nitrobenzoyl azide

  在甲苯中加热邻乙酰氧基苯甲酰叠氮化物 6-10 导致 Curtius 反应，随后恶唑酮环闭合，同时乙酰基从氧迁移到氮，生成 3-乙酰氧基苯并[d]恶唑-2(3H) -ones 11-15，用热的稀盐酸水解，得到苯并[d]恶唑-2(3H)-ones 17-21。2-羟基-5-硝基苯甲酰叠氮化物 (22) 在甲苯中的热反应最终产生 5-硝基苯并[d]恶唑-2(3H)-酮 (20) 和 5-硝基苯并[d]异恶唑-3(2H)的混合物)-一 (23)。

• Zwitterionic Ring-Opened Oxyphosphonium Species from the Ph₃P–I₂ Mediated Reactions of Benzo[<i>d</i>]oxazol-2(3<i>H</i>)-ones with Secondary Amines
  作者：Mookda Pattarawarapan、Nittaya Wiriya、Saranphong Yimklan、Sirilak Wangngae、Wong Phakhodee

  DOI：10.1021/acs.joc.0c00211

  日期：2020.5.1

  Ph3P-I2-mediated reactions of benzo[d]oxazol-2(3H)-ones with acyclic secondary amines. The structure of one of these compounds was unambiguously confirmed by single-crystal X-ray analysis. Thermolysis of the betaines gave rise to 2-dialkylaminobenzoxazoles with concomitant loss of triphenylphosphine oxide, suggesting their possible role as intermediates in an alternative reaction path.

  代替预期的取代的2-氨基苯并[d]恶唑，首次从Ph3P-I2介导的苯并[d]恶唑-2（3H）-酮与无环仲醇的反应中分离了相对稳定的开环氧phosph甜菜碱胺类。通过单晶X射线分析清楚地证实了这些化合物之一的结构。甜菜碱的热解产生了2-二烷基氨基苯并恶唑，同时伴随着三苯基膦氧化物的损失，表明它们在替代反应路径中作为中间体的可能作用。
